And yet all traditions have to start somewhere. Santa Claus was not always a fat, rosy cheeked man with a white beard and a red suit until he showed up in a Coca Cola ad In the early 1930s, the same decade kids started trick or treating. Auld Lang Syne didn't become the New Year song until Guy Lombardo's band played it on the radio in 1929, and Mariah Carey's All I Want for Christmas couldn't top the charts every December until it was actually released in 1994. And one of the fall season's most sippable autumnal traditions did not become established until 2003.
Don Martin
Could you have ever imagined the cultural shift that happened when Starbucks debuted the pumpkin spice latte? Like, just the obsession. Wow.
Willa Paskin
Don Martin is a writer and podcaster who has thought a lot about the Starbucks pumpkin spice line since he started ordering Frappuccinos in college.
Don Martin
Back then I was all about like, give me a big frothy pumpkin spice flavored, basically milkshake that like somebody had whispered the word coffee. Next to I think I have a photo of me with some terrible hair of like French of like French kissing pumpkin spice Frappuccino.
Willa Paskin
How do you French kiss a pumpkin spice Frappuccino? Just like a lot of tongue.
Don Martin
Listen, I was young. I'm not proud. We all do things for love, and.
Willa Paskin
Donna's not the only person who has ever fallen hard for this beverage.
Don Martin
It's Officially, PSL season pumpkin spice is.
Carolyn Super
Back at Starbucks, y'.
Willa Paskin
All. First pumpkin spice of the season. Oh, my God. Oh, my God. According to Starbucks, the drink originated in a group brainstorm convened to try and recreate the success of a peppermint mocha drink. The pumpkin spice latte was intended to just be a one off released that fall. But when the psl, as Starbucks refers to it, was introduced, something, if you stop to think about it, really bizarre happened. This sweet spiced coffee drink became a lifestyle phenomenon.
Don Martin
I don't think anybody could have, like, prepped for, like, the seismic cultural shift that that was.
Willa Paskin
By the 2010s, hundreds of millions of drinks had been sold, and pumpkin spice was not just in coffee cups, it was everywhere. Pop tarts, Pringles cereal, beef jerky.
Don Martin
Do you remember that era a few years ago where there was pumpkin spice toilet paper?
Willa Paskin
I do not.
Don Martin
Oh, my God.
Willa Paskin
I have a gross question which is like, how do you know it's pumpkin spice toilet paper?
Don Martin
That was my question as well. So I did, of course, have to buy it for science. It just. It smells like it.
Willa Paskin
And putting pumpkin spice into consumer products was only part of the PSL's cultural reach. For many, the drink had become one of the very hallmarks of autumn, where.
Don Martin
It'S like, oh, the seasons are changing. Oh, God, I have to have this in order to start fall. You know, like, I need to pull out my knee high boots, I need to get my puffer vest, and I need to go and get that pumpkin spice latte, like, to celebrate the changing of the seasons.
Willa Paskin
It's officially fall, AKA pumpkin spice season.
Carolyn Super
Let's get the first pumpkin spice latte of the year.
Willa Paskin
The first sip instantly made me want.
Carolyn Super
To pull out all the fall decor.
Don Martin
It tastes like fall. It's a big cup of fall. Or at least it used to be.
Willa Paskin
Because for all the excitement that to this day greets the PSL's annual arrival, it's also accompanied by a certain amount of grumbling and suspicion. And I'm not just talking about the eye rollers who find it and the women who love it unbearably basic.
Don Martin
There's usually a mention of, I remember the pumpkin spice latte tasting better, and I went and tasted. I hadn't had one in years and I wanted to go back and try it, and it just doesn't taste the same. Everyone's saying that they changed the Starbucks pumpkin spice latte.
Willa Paskin
Yeah, that's why it tastes different.
Don Martin
There is something different about that. It's very, very strange. Very, very weird flavor.
Willa Paskin
It's not normal Reddit threads, Facebook posts, TikToks, YouTubes, and Instagram Reels are full of people claiming that something is off that this pumpkin spice latte, this beloved fall ritual, is just not what they remember. And instead of chalking this up to crankiness or faulty memories, it turns out.
Don Martin
There'S a reason for that. And now it's just a little bit worse.
Willa Paskin
This is Decoder Ring. I'm Willa Paskin. Some things just scream Autumn though. Exactly what may be different for all of us? Personally, nothing says fall to me like sweaters, slippers, and a screening of one Harry Met Sally. But maybe you're a football fan are really into spooky Season an apple picker, A leaf peeper. A candy cornaholic. Whatever it is, fall just seems to have a lot of these homey signifiers. And in today's episode, we're looking closely at three of them. First, we'll get to the bottom of whatever's going on with the taste of the pumpkin spice latte. Then we'll gaze deep into the enigma hiding inside a beautiful fall leaf. And finally, we'll finish off with some serious questions about the availability of an elusive cookie. So today on Decoder Ring, snuggle up to three cozy mysteries. It's fall y'.

So when we left off, Don Martin and many others had noticed that something seemed to have happened to the canonical fall beverage, the pumpkin spice latte. So the pumpkin spice is different this year.
Don Martin
Everyone keeps saying that it tastes wrong.
Carolyn Super
I'll be honest, the pumpkin spice lattes weren't as good.
Don Martin
It's worse than last year.
Willa Paskin
And while most people didn't do anything with this information besides staging a personal taste test on TikTok, Don is not most people. He decided to investigate and what he found led him back to 2014.
Don Martin
A lot of this started in the heyday of like Facebook, back when like memes and infographics were becoming a primary method that people consumed news and information. And there was this blogger who goes by food bait.
Carolyn Super
Hi, I'm Vonni from Foodbabe.com I'm about to call the Lean Cuisine headquarters and try to find out what exactly is natural about their honestly good product.
Willa Paskin
Food babes real name is Vani Hari and she had built a large following on social media as a self styled investigator of what she deemed to be questionable ingredients. Hari had already been part of successful campaigns to get Subway to remove an additive from its bread and to get artificial dyes out of Kraft macaroni and cheese.
Carolyn Super
Yellow number five and yellow number six specifically are known carcinogens. That means it's linked to causing cancer.
Willa Paskin
In 2014 she posted a meme that went viral. It was meant as a wake up call. The PSL was not what it seemed.
Don Martin
So there was like a picture a Starbucks pumpkin spice latte and it was like sliced down the middle and you could like see all the layers of the nefarious ingredients in there. Like there's these dyes and these chemicals.
Willa Paskin
This meme pointed out that the PSL contained two doses of caramel coating which it annotated as being considered a carcinogen. Hari also claimed it contained a toxic dose of sugar and called out other food additives. But there was one complaint that really stood out.
Don Martin
Food babes specifically said, do you know what isn't in the pumpkin spice latte? It's pumpkin.
Willa Paskin
And that was true. There was no actual pumpkin in the pumpkin spice latte. And for a lot of people this was shocking. Okay, do you know what pumpkin spice is? Let me educate you real quick. Pumpkin spice doesn't actually have any pumpkin in it. Wait, wait, wait, wait, wait. So there's no pumpkin in pumpkin spice? Pumpkin spice foods inexplicably seem to grow more omnipresent even though there's no actual pumpkin in the drinks. But this was not news to Don.
Don Martin
I never assumed it had pumpkin in it. Pumpkin spice was always the spice blend. It's the spice blend that turns pumpkin into pie ingredients. Like, I never once thought it had pumpkin in it.
Willa Paskin
Bakers have been referring to this mixture of cinnamon, clove, ginger, nutmeg, and allspice as a pumpkin spice blend since at least the early part of the 20th century. And Starbucks hadn't been keeping the lack of pumpkin a secret. But when the Food Babe meme dropped, the message was clear.
Don Martin
They're lying to you. Starbucks is lying to you about what's in their product.
Willa Paskin
The backlash was on.
Don Martin
Oh my God. It went. I mean, it was everywhere. It was all over social media. The news covered it.
Willa Paskin
Hari made a big splash earlier this fall when she posted the previously undisclosed.
Don Martin
Ingredients of Starbucks pumpkin spice Latte.
Carolyn Super
Seeing that a coffee drink is colored with this ammonia based art artificial food dye is very alarming that they are putting this chemical in my drink.
Willa Paskin
Ultimately, it generated enough concern in hubbub that Starbucks was forced to respond.
Don Martin
They were like, well, we're going to take your concerns to heart and we're going to reformulate our pumpkin spice latte drink. And we need to make this right by including the missing ingredients that they should have added in the first place.
Willa Paskin
Namely pumpkin.
Don Martin
Namely pumpkin.
Carolyn Super
Starbucks has announced it will include real pumpkin in its pumpkin spice latte. No artificial coloring. Didn't know it didn't have any real pumpkin at the coffee chain. Will make this change after a popular food blogger known as the Food Babe questioned the drink's ingredients.
Willa Paskin
And so since 2015, the PSL is indeed not the same PSL that America first fell in love with.
Don Martin
And I'm a tell ya, people can tell that little bit of extra pumpkin. I don't, I don't know, it just, it just makes it taste weird.
Willa Paskin
Yeah, it is a weird thing to.
Carolyn Super
Put into your coffee.
Don Martin
It is like, I mean, raw pumpkin is what we gave my diabetic dog. Raw pumpkin doesn't taste good.
Willa Paskin
And Don is not interested in all of this just because of the taste. He sees this whole incident as a harbinger of things to come. Because the uproar about what is really in the PSL has since recurred many times over in far more consequential areas.
Don Martin
We present a problem people didn't even think that they had because it's not a real problem and tell people to be scared and tell people not to trust. And that in and of itself is a breeding ground for misinformation, disinformation, and for a whole host of other things.
Willa Paskin
Vani Hari, the woman known as Food Babe and the person who kickstarted the outcry against the pumpkin spice latte, has since become one of the major players in RFK Jr. S Maha movement, and she even spoke at the White House earlier this year.
Carolyn Super
This has got to start day that American companies are poisoning us with ingredients. Americans deserve safe food and our children.
Willa Paskin
Deserve she's been criticized for inaccuracies, fear mongering, and making claims rejected by food scientists. But she's also clearly tapping into genuine anxieties about what we're putting into our own bodies. Getting a small dose of pumpkin added to a sugary, caffeinated decadent treat that no one ever should have construed as healthy in the first place is an odd accomplishment. It's one that doesn't do much but make the PSL a little thicker, goopier, stranger. But maybe that makes the PSL even more exemplary of our current moment when anxiety and mistrust lead people to be skeptical of traditional expertise and yet simultaneously credulous of individuals doing their own research. You get weird outcomes, compromises, workarounds. You get metaphorical pumpkin puree in your coffee.
Don Martin
I think all of the headache of the pumpkin spice latte eventually made me break up with the pumpkin spice latte. Like maybe, maybe we don't need everything to be pumpkin spice.
Willa Paskin

As the weather changes in certain parts of the world, as the days shorten and get colder, the leaves of deciduous trees begin to die. And only then do we get very excited about them. Look at the reds on that tree. Just beautiful. And then we got some oranges, we've got some yellows.
Carolyn Super
This is my favorite time of year.
Willa Paskin
It's this, the fall foliage.
Carolyn Super
These colors go straight through my retina and feed my soul.
Willa Paskin
You know what just rips, dude, is just like some foliage, dude. Like, how. How does a leaf even do that? How is it even that color, dude? Annually, millions of leaf peepers descend upon places like Vermont and New Hampshire, where the foliage fireworks are most pronounced. Just to take it all in. We get to look down and kind of watch the colors wash down the hills.
Carolyn Super
Yellows, oranges, reds.
Willa Paskin
It's just. It's so beautiful. This brilliant display has inspired paintings, photographs, poems, and songs.
Simcha Levyadun
The falling leaves drift by the window the autumn leaves of red and gold.
Willa Paskin
And it's also inspired a seemingly simple question. Why do leaves change color in fall? Why do leaves change color in the fall? Why do leaves change colors?
Grace Dewey
Is it because they're tired of being green?
Willa Paskin
And you'd think a kid's question like this would have a simple answer, but as we have learned, and you're about to, it does not. It turns out that, like our other people seeing the same shade of blue as me, it's a bona fide stumper. It gets right to the matter of how we know what we know. So it's an adult question, really, and the complications begin immediately because there has long been an answer provided one you might already know yourself. The leaf is one of the most.
Simcha Levyadun
Important parts of a plant.
Willa Paskin
Leaves capture the energy of sunshine and use it to make food. The traditional explanation starts with why leaves are green in the first place. And it's that to make their food they need a chemical. It is called chlorophyll. Chlorophyll has the power to trap the sunlight and harness its life giving energy. And chlorophyll is what makes plants green. And so leaves have a lot of green chlorophyll inside them. They have other pigments in them too. The story goes, but you can't see the yellows and reds and oranges because the green is so dominant. That is for most of the year.
Simcha Levyadun
All summer the leaves stay green.
Willa Paskin
But as the days get shorter, the down the chlorophyll and begin to pull all their energy and nutrients back into their trunks. And so the green starts to fade. And then suddenly all the hidden colors are revealed.
Simcha Levyadun
And so the leaves become more colorful than ever.
Willa Paskin
This has long been the explanation for the vibrant colors of autumn. It's just a side effect of them preparing for winter. One that, lucky for us, happens to be very beautiful. I actually remember learning this in science class when I was younger and I wasn't alone.
Simcha Levyadun
What I was taught in a course of gaobotany was the green disappears. You see the red and yellow because they are not masked anymore by lots of green.
Willa Paskin
Simcha Leviadun is an emeritus professor of botany and archaeology and he heard the same story well into graduate school.
Simcha Levyadun
This was the common belief.
Willa Paskin
But he says there's long been a problem with this belief. It's incomplete. It does accurately describe what's happening when a leaf turns yellow or orange. Pigments that have been lurking inside the leaf the whole time. But it does not explain why a leaf would turn red. Because the red pigments are not there all year. In fact, trees do not even begin to produce them until the fall.
Simcha Levyadun
They are synthesized in the leaves before they are shed.
Willa Paskin
The chemical that produces the red is called anthocyanin. Anthocyanins are what give fruits like blueberries and grapes their colors. And they take a lot of effort.
Simcha Levyadun
To make not just energy, but time and materials to construct those molecules.
Willa Paskin
Why would a tree bother to do this right before its leaves are about to drop anyway?
Simcha Levyadun
You have an old car, you want to send it for metal recycling or whatever, or just dump it. You don't put money in it before you dump it.
Willa Paskin
But that's exactly what the trees seem to be doing, making all this costly red for their leaves even as they are dying. It's a head scratcher and one that scientists had long been aware of, but that they hadn't really gotten to thinking about.
Simcha Levyadun
People were not really interested in this. I mean, it was a byproduct, nobody paid attention.
Willa Paskin
But that changed around the turn of the millennium.
Simcha Levyadun
This was the time that people started to understand that something is happening though.
Willa Paskin
The person most responsible for a new burst of interest in autumn leaves was a renowned evolutionary biologist named W.D. hamilton.
Simcha Levyadun
The more influence life has in the universe, the better as far as as I'm concerned. So it would be nice to think of the whole world as a one.
Willa Paskin
Living organism in some sense. Hamilton was a giant in his field, generating all sorts of creative theories about the workings of evolution. He was one of the first people to argue that there was an evolutionary basis for altruism. He thought sexual reproduction evolved as a way to avoid parasites. And he proposed novel explanations about behavior of everything from wasps to algae. And in the late 1990s, he turned his attention to fall foliage. If a tree is expending energy to change colors, he thought, then the tree must have evolved to do so for a reason.
Simcha Levyadun
What was so important was that he said that the colors has a function.
Willa Paskin
But what could that function be? Well, we have long known that plants and animals use color to communicate. Dazzling flowers tell bees and butterflies come here. Brightly colored poison dart frogs and coral snakes signal stay away.
Simcha Levyadun
They advertise their qualities. They say, listen, I don't hide myself, it's better don't deal with me.
Willa Paskin
Hamilton figured if the natural world is full of species communicating with one another via color, maybe autumn leaves were a communique too. Maybe the trees weren't just inadvertently putting on a show for us. Maybe they were defending themselves. And so he and a couple colleagues at Oxford co authored a paper with a brand new theory.
Simcha Levyadun
They propose an anti herbivory hypothesis.
Willa Paskin
What does anti herbivore mean?
Simcha Levyadun
Means it stops herbivore from eating the plants.
Willa Paskin
And the paper made a guess as to which pesky herbivores they might be defending themselves from.
Simcha Levyadun
There's an insect that all gardeners loathe, Aphids.
Willa Paskin
Aphids are a family of SAP sucking pests. There are more than 5,000 different species of them and some are known to cause tremendous damage. They're a nightmare for anyone growing veggies. They pierce leaves and stems with their stylet and suck out sugary SAP. Hamilton and his colleagues hypothesis was that the bright colors in autumn leaves were to keep aphids from doing exactly this, that the colors were basically a warning sign to deter aphids, telling them, hey, don't suck your SAP here. Their paper was published by the Royal Society in 2001, shortly after Hamilton died. It cited data that seemed to suggest that aphids behaved differently depending on a leaf's color. And suddenly, scholars started to pay attention.
Simcha Levyadun
It was controversial. Very quickly, there were several dozen papers published with some nasty quarrels. Some papers were not so polite.
Willa Paskin
Botanists, who tend to study the specifics of how plants really work, faced off against ecologists, who tend to take a broader view of species interactions.
Simcha Levyadun
And it's very good in science when people start to argue because it intrigues many other, and people start to think so new ideas are coming, are added to this theoretical soup.
Willa Paskin
Soon, scientists had to mix our metaphors, chewed some holes in the original soup. That first paper had made no distinction between yellow and red leaves. It said aphids might be deterred by both. But other scholars proved within a year or two that far from deterring aphids, yellow seem to do the opposite.
Simcha Levyadun
Yellow attracts aphids because when it's becoming yellow, it's full of amino acids and many aphids drink it like we drink some juice with a straw.
Willa Paskin
So yellow did not seem to be defensive, at least when it came to aphids. But what about red? A 2008 study showed that aphids did appear to find red leaves less attractive than green ones. And there have been many, many ideas proposed as to why. It could be that red is there to cover up the yellow aphids like so much, or that the red just makes the leaves appear dark and thus invisible to bugs. Or maybe it's not the color itself, but the chemicals, smells, taste, and toxins that can go with it. Simcha has studied the research extensively, and he believes all 25 years of work work adds up to a basic confirmation of Hamilton's original hypothesis. At least one of the functions of autumnal leaf colors, and red in particular, is a defense against pests, not only aphids.
Simcha Levyadun
Many, many, many types of herbivores are deterred by red. The red says, pay attention, red is danger.
Willa Paskin
He thinks the evidence shows caterpillars and fungi also get the message in various ways and that the trees are protecting themselves against all of them.
Simcha Levyadun
And I think this is enough.
Willa Paskin
But not enough for everyone.
Suzanne Renner
If there was a person predisposed to believing in signaling from plants to herbivores, it's me of Course, plants signal to insects.
Willa Paskin
Suzanne Renner is a botanist and an honorary professor of biology at Washington University in St. Louis, who first became enamored with her field by observing bee and flower interaction.
Suzanne Renner
But there's so many implausible aspects of the idea that red or yellow leaves in the fall would signal to insects. There is no evidence.
Willa Paskin
Suzanne doesn't buy, that a tree would be expending all this energy to ward bugs off of leaves that are on the verge of dropping anyway.
Suzanne Renner
We are talking about leaves about to be shed from which the nutrients are being removed. Why would any tree have a selective advantage from telling some aphid to either eat it or not eat it?
Willa Paskin
Besides, she argues, in the autumn months, aphids don't care about leaves. What they care about is bark.
Suzanne Renner
They're looking for a crevice to put their eggs in. They are not looking for leaves. They are not feeding. They're concerned about putting their little eggs in a protected place so it will be able to withstand frost.
Willa Paskin
Furthermore, she says that in the nearly 25 years since the paper came out, nobody has been able to identify a species of aphids that actively avoids red fall leaves.
Suzanne Renner
I think it is implausible that we will ever find an herbivore, pollinator, or fruit disperser reacting to the leaf red. I think it is completely implausible. Completely implausible.
Willa Paskin
But just because she doesn't think the red is deterring pests does not mean that Suzanne thinks the red in leaves isn't doing anything. It's just that her research has led her to a different conclusion. About what? It started with some observations about where leaves turn red. As you may or may not be aware, autumn's color palette is different depending on where you live. When people travel from all over the world to Vermont, they're seeking out multicolored forests streaked with red. But that's a different view than the one you might get in, say, Colorado.
Suzanne Renner
You never see a red leaf in Colorado. I'm only exaggerating very, very slightly. All of Colorado is yellow.
Willa Paskin
And it's not just a matter of how far north you are. Boston and Rome are on the same latitude, but you won't spot many red leaves along the Via appiah. And when Suzanne conducted research on a species level, she confirmed that this was the case.
Suzanne Renner
What we found, both experimentally and by monitoring, is that many more species in eastern North America produce the red color than European and Asian tree species.
Willa Paskin
To be clear, it's not that all trees in eastern North America turn red in the fall, and There are Asian species that do turn red, like the Japanese maple. But in general, Suzanne found there was a pattern.
Suzanne Renner
So why could that be?
Willa Paskin
Why would a tree species that evolved to survive in New England be more genetically predisposed to have red leaves than a tree that evolved to survive in Italy? And she realized the answer is light.
Suzanne Renner
This same latitude in eastern North America will get more incoming light in September compared to Europe.
Willa Paskin
It may sound strange, but it's true. The Northeast in fall is exceptionally sunny. It has to do with how land masses, oceans, and wind affect our cloud patterns.
Suzanne Renner
And this is highly statistically significant. Okay, and so then if you have all this light coming in in September, October, then it makes sense that you would want to protect your leaves against.
Willa Paskin
Excessive light, just as it is with humans. Excessive light can be harmful for trees. It can degrade the nutrients the trees are trying to p pull out of their leaves.
Suzanne Renner
Excessive light can damage nuclei, can damage the cells.
Willa Paskin
And Suzanne knew there was a chemical that had been shown to protect a plant against the dangers of excessive light. Anthocyanin. The very same chemical that makes leaves in the fall red. And so Suzanne had her answer. In 2019, she co authored a paper arguing that the red wasn't acting as bug spray. It was sunscreen.
Suzanne Renner
Having this sunscreen, this red anthocyanide sunscreen in your leaves would allow you to pull back the nutrients for a little longer, maybe seven days longer.
Willa Paskin
And Suzanne says this is the answer to the mystery of why leaves turn red.
Suzanne Renner
Isn't it a wonderful story? Isn't this all wonderful evidence of how plants have managed, managed to evolve strategies to handle all these terrible conditions they are exposed to? Isn't that wonderful? I think it's absolutely wonderful.
Willa Paskin
Simcha Levyadoun doesn't deny the sunscreen explanation.
Simcha Levyadun
Yes, why not?
Willa Paskin
But he's not too troubled that in the 25 years since the herbivore hypothesis was first proposed, there's been no new experimental evidence suggesting any actual pest is deterred by red leaves. It is, as ever, hard to prove.
Simcha Levyadun
A negative, because the animals that are deterred by something are not there. So you cannot measure them because they are not there.
Willa Paskin
He's certain that the bug spray explanation can be true at the same time as the sunscreen one, that a red leaf can protect against sunlight and simultaneously defend against aphids and caterpillars and fungi.
Simcha Levyadun
Listen, you have a stove at home. You can cook potatoes, and you can cook a chicken or pork or beef. I mean, you have a tool. Why not use it for several functions?
Willa Paskin
I have to confess, at this point, as a non scientist, I felt properly unsettled. Discovering that we could not reach consensus on even the simplest seeming kids question surprised me. My instinct was to make like Simcha and say, hey, why can't all of these things be true at once? But maybe that's an oversimplified dodge. Just because a stove can cook sweet potatoes and chicken and carrots all at the same time does not mean that it is. It was all enough to make me want to go out and look at some actual leaves. Should we go through the woods?
Suzanne Renner
Yeah, sure. Right through here.
Willa Paskin
I took a walk through Brooklyn's Prospect park with Malcolm Gore. He's the Prospect park alliance arborist, which means he takes care of the park's 30,000 trees. What's those ones over there that are going.
Malcolm Gore
Those. That looks like a sweet gum to me. I like to call sweet gums the rainbow tree because they, like, change on a gradient from red to yellow to purple from the top down. So they're like, gorgeous.
Willa Paskin
The leaves in this park and elsewhere are not aware of the debate raging around why they do what they do. They're not aware that even this seemingly simple matter has run afoul not only of the limits of our knowledge, but the limits of our ability to agree about that knowledge. They just keep doing their thing.
Malcolm Gore
The maples are classic, and they have different variation in their color.
Willa Paskin
Like, two of them look like they have, like, that have frosted tips. Yep. The other one is, like, mostly red, right? Yeah.
Malcolm Gore
A tree that we have in Prospect park that is not around in a lot of other parts of New York is black gum or tupelo. It's kind of more of a southern tree. And they get this, like, iridescent red. It's like they almost like, glow with their, like, reddish purplish hue when they.
Willa Paskin
Change color and all the color. The reason that people really care about autumn leaves in the flower first place is what Malcolm thinks is most fascinating too.
Malcolm Gore
It's just a beautiful thing. Like, for me, as a practitioner, I'm not a scientist, I, you know, maybe trees are just doing it because they like to be pretty. Like, you know, it's their. It's their showoff season or something like that.
Willa Paskin
Like peacocks.
Malcolm Gore
Yeah, exactly. It's possible that they are doing it for. For us, you know, probably not.
Don Martin
But.
Willa Paskin

So as you've heard, for some fall is a time of pumpkin spice lattes or of changing leaves, but for others still, autumn means something else entirely. My mother. She really does associate it with the release of Malamars.
Grace Dewey
I just love chocolate.
Willa Paskin
The first voice you just heard belongs to Lauren Tarr. I am a writer and a editor.
Grace Dewey
And a blogger and I'm Grace Dewey and I'm an 82 year old mother of this darling daughter, almost 83.
Willa Paskin
So we should clarify that so. And for Most of those 83 years, Grace has been a fan of the Malamar, a cookie based upon the classic campfire treat, the s'. More. It's a disc of chocolate sitting atop a round graham cracker bottom. And. And both are coated in chocolate. They look kind of like brown hockey pucks. And Grace finds them totally irresistible.
Grace Dewey
I leave them in the refrigerator, and I kind of pick at them all day long.
Willa Paskin
How many do you think you eat a day? I'm not so sure she's going to be honest about that answer.
Grace Dewey
At least a half a dozen.
Willa Paskin
Do your friends know about this?
Grace Dewey
Of course they do.
Willa Paskin
Do they come over for a Malama?
Grace Dewey
No, no, no. I'm not sharing.
Willa Paskin
And Grace is not alone in her Malamar obsession. These are Malamars, the best cooking known to man.
Don Martin
Every single time that I see them.
Simcha Levyadun
I always have to buy two boxes.
Willa Paskin
The marshmallows, the cookie, the chocolate is like the trifecta of flavors and textures.
Suzanne Renner
This is a superior snack.
Willa Paskin
And the testimonials aren't just on TikTok. They're all over popular culture. Well, why don't you just say something so I can become hysterical? Eat a box of Malamaz and get it over with. They're beloved by both the Golden Girls and the Gilmore Girls. What the hell is this?
Carolyn Super
My birthday Malamar's, she says.
Simcha Levyadun
Like I should just know this.
Willa Paskin
They've been celebrated in When Harry Met Sally got Malamar's the greatest cookie of all time, and even Tony Soprano guards them jealously. I do something wrong Sunday, my house.
Don Martin
Box of Malamars on the counter, empty.
Willa Paskin
You think I don't know it was you? Despite having so many fervent admirers, you may not be familiar with them at all. And that's because they are largely a regional delicacy, even though they are now made by Mondelez, the multinational food company that also makes Oreos and Ritz crackers and Sour Patch Kids. They are sold almost exclusively in the Northeast. In fact, Grace was introduced to them as a little girl in Brooklyn. Malamars were her grandmother's favorite.
Grace Dewey
And the funny thing is, growing up, I didn't realize that it was a seasonal thing.
Willa Paskin
And that's the other reason Malamars may be hard for you to spot. Their yellow boxes don't arrive on shelves until right after Labor Day, and they disappear again in March.
Grace Dewey
And once I discovered that I got as many as I can, I'm obsessed with getting them on sale, and I. I stackpile them in my pantry.
Willa Paskin
Like, are you Paying attention to, like, it's about to be Malamar season. Like, do you know when it's coming?
Grace Dewey
Oh, yes, I definitely know when it's coming.
Willa Paskin
How many do you think you get a season?
Grace Dewey
Probably a dozen.
Willa Paskin
No, you have a dozen in your pantry right now.
Grace Dewey
I don't like to tell my daughter.
Suzanne Renner
Everything.
Willa Paskin
But Grace is not stockpiling boxes just for her own pleasure. My mother's obsession with Malamars definitely grew when she realized her grandchildren enjoyed these. They all have come to know as.
Carolyn Super
Soon as September comes, they will be.
Willa Paskin
Having a package delivered to their door filled with Malamars from their grandmother.
Grace Dewey
I'm hoping that they don't share with.
Willa Paskin
Their roommates, and that's because of how hard these boxes are to come by. Amassing her annual cash has required some craftiness on Grace's part because she is far from the only person who is so keen on Malamar's. They're treated like a precious commodity in some places. Her old supermarket on Long island put strict limits in place. Customers could purchase only two boxes at a time.
Grace Dewey
So my strategy for that would be to take the tool that I was allowed to get, put them in the car, and go back into the store. But then I had to find a different checkout cashier so that she didn't recognize me and say, oh, you have already here and you already had your two limit.
Willa Paskin
She has been known to go to different grocery stores in the same week if that strategy didn't pan out the way she hoped. And this brings us to the mystery at the heart of the Malamar. Why on earth is Grace required to jump through all these hoops for a cookie? Why are Malamars sold like this? Why can you only get them for half a year? I thought I knew part of the answer. My dad's a Malamar fan himself. Every year when they first go on sale, he snags a few boxes. I have to admit that I don't find them to be particularly special. But we have talked many times over the years about their strange schedule, which does go back more than a century. And that's because it's a solution to a problem that has plagued Malamars since they were first invented. Malamars were introduced by the National Biscuit Company, later Nabisco in Hoboken, New Jersey, all the way back in 1913. Then, as now, a Malamar was a mound of marshmallow sitting atop a graham cracker bottom and covered in chocolate. But something back then was not the same, especially in the summer, in the intense heat.
Simcha Levyadun
Food preservation became a problem of increasing gravity, milk size, meat spoiled and vegetables withered.
Willa Paskin
And you can only imagine what might have happened to the chocolate in a Malamar. And so, to avoid the cookies turning into a gooey, dirty mess, Malamar's could only be distributed in the cooler months. And that schedule has remained in place for the past 112 years. It's remained even as the packaging has changed. It's remained even as the Behren company has gone from Nabisco to Kraft to NOW Mondelez. And that whole time, whenever the cookie's various owners have been pressed on its quirky and ancient scheduling, they have insisted this is just what the Malamar requires. It is one of the only cookies covered in pure chocolate.
Don Martin
And because it's real chocolate and such.
Willa Paskin
A thin coating of chocolate, Malamars aren't.
Don Martin
Available during the summer months. You can only find them on store.
Carolyn Super
Shelves between October and April.
Willa Paskin
That's a newscast from 2000. The then owner, Kraft, confirmed to another reporter that Malamar's had to be baked only during cooler weather because the pure chocolate is susceptible to excessive heat. And in the summer, the chocolate would apparently melt and the cocoa butter would leach out, turning the cookie white. That does seem like a fate a Malamar should try to avoid. And yet a quick perusal of any corner or grocery store reveals tons of chocolate products for sale all year round, none the worse for wear. And that's not some brand new human capability. Modern dairies now, by the use of refrigerated and ice trucks, transport the products to the surrounding territory speedily and efficiently. The refrigerated truck was invented all the way back in 1938 by a guy named Frederick McKinley Jones, a black engineer who whipped one together in just a few weeks and then co founded a refrigerated truck business that by the 1950s had perishable food shuttling across the country year round. It may have taken a few more decades to perfect chocolate that would melt on hot store shelves, but thousands of other chocolate products seem to have figured it out. This is the most powerful nation on earth. Can't we figure out a way to refrigerate Malamar's Properly? A 2004 episode of Conan featured a whole rant challenging the company line on the stage seasonality of Malamars. I should be able to eat Malamar cookies anytime I want, even in the summer. So what gives? Are Malamars just some kind of purist holdout chocolate traditionalists who don't want anything to do with preservatives? And newfangled non melting technologies. I needed to figure out how this cookie really crumbled. And so I reached out to Carolyn Super, a brand manager at Mondelez, who oversees Malamar's.
Carolyn Super
Among other cookies, honey made graham crackers, Nilla wafers, Fig Newtons. So it's. It's a big cookie job.
Willa Paskin
Were you familiar with Malamars from your childhood?
Carolyn Super
I was not. I was actually. I grew up in Idaho, so I had never even heard of Malamars before I took this job. And I. The first time I had them was today.
Willa Paskin
Really?
Carolyn Super
Yes. Yeah.
Willa Paskin
That's incredible.
Carolyn Super
Well, since this job, I started it in February, and as you know, it's a seasonal item, so I haven't really even had a chance to try them until now.
Willa Paskin
What did you think?
Carolyn Super
I loved them.
Willa Paskin
After her review, we did get down to the business at hand. Why are Malamars sold this way?
Carolyn Super
Part of the reason why it's only available in the fall is it's actually real chocolate as opposed to some other products out there. So, so traditionally, we couldn't ship it in the summer because the real chocolate would melt. So we had to wait until like, those leaves were falling to start shipping it out.
Willa Paskin
So, okay, yes, the melting was genuinely the reason we couldn't have Malamar's year round. But what I really needed to know from Caroline was, is that still true in 2025?
Carolyn Super
No. We have the technology to be able to ship the products full year around.
Willa Paskin
So if Malamar's can be sold year round, why aren't they? Why is this cookie being sold like it's 1914? Caroline says part of the answer actually does have to do with the Malamar's chocolate, though not how melty it is. It's about how it's manufactured.
Carolyn Super
So there's a biscuit at the bottom and then there's marshmallow on top. And then it's. The technical term we use is it's enrobed in chocolate.
Willa Paskin
Picture little naked Malamars, just a graham cracker and a puff of white marshmallow. And imagine they are waiting in the Malamar factory to get dressed, enrobed in chocolate.
Carolyn Super
And then just like the enrobing process, it's just you, like, literally dunk it. It's a very manual factory. So there's just a lot of people who are always, like, there, as opposed to some other factories that have a lot of machines.
Willa Paskin
But the very manual Mondelez factory in Toronto, where the Malamars get enrobed in, has to dress other cookies too.
Carolyn Super
We share the manufacturing location with our other brands. So there's Oreo and Robed that runs on that line. Pinwheels run on that line. So we also have to balance how much we can really run at one time.
Willa Paskin
So I mean, what you're saying is like, because Malamars are made in a factory that has like enrobing capabilities, when Malamars are not in production, you are using those enrobing capabilities and a whole bunch of other cookies. And if you were running Malamars all.
Carolyn Super
Year, you couldn't do that 100%. So Malamars we run mostly in July and August. We run 80% of all of the volume in July and August.
Willa Paskin
In the summer.
Carolyn Super
Yep, exactly.
Willa Paskin
See, they're not really worried about melting and they don't want to bump other cookies like chocolate covered Oreos from access to the company's enrobing facilities. But presumably they could and would rearrange their production schedule if it made financial sense to try churn out Malamar's year round. So there's something else too, maybe the biggest factor of all, and it's that selling these cookies six months of the year, selling these cookies that are handed down from generation to generation that have been sold this way for over 100 years, that's part of what makes Malamar so desirable in the first place.
Carolyn Super
I think a lot of the fad and the excitement is that they aren't available year round.
Willa Paskin
Malamars are scarce. And so when they do come around after Labor Day, it's an event. An event customers are eager to promote all by themselves.
Carolyn Super
I have been on the hunt for.
Willa Paskin
These cookies for weeks in the grocery store yesterday and I saw the Malamars.
Don Martin
And I got really excited because like it's Malamar season. They're back.
Willa Paskin
I'm hopped up on the Malamars. Do you ever eat the Malamars, John? What's that? You've never had a Malamar? It's a seasonal cookie.
Carolyn Super
We have that talkability where we don't actually do a ton of marketing. We're just this tried and true product that comes back every year at the same time, always after Labor Day. And it's really the word of mouth marketing. Some retailers actually cut a spot on their shelf for Malamar's. They plan for that space to be open just for us to be on shelf. Like shoprite has this in mind.
Willa Paskin
Like everybody's in it together about like the seasonality of Malamar 100%.
Carolyn Super
So I think that the fad would, I think, kind of die in the interest and people wouldn't be looking for them as much in the fall.
Willa Paskin
The funny thing about all of this is that Malamar's, by not changing their sales strategy for a century, has ended up with the most cutting edge way to sell anything right now. Organic viral marketing built around scarcity. This is how sneaker drops work. It's Monday morning, so here's all the sneakers dropping this week. Just like every other release week we're talking about just how limited are the.
Simcha Levyadun
Air Jordan 4 rare air.
Willa Paskin
Check out these kicks that were just delivered to my house. They're one of 100. It does seem like a very newfangled way to sell an old cookie, right?
Carolyn Super
And we were the trendsetters.
Willa Paskin
And for Malamar's, it's still working.
Carolyn Super
We actually sell like $13 million worth of the product just from September to like February, March when they become unavailable, which is sometimes the size of our other cookie brands that are sold full year.
Willa Paskin
Around 13 million is about the same amount that Pinwheels make. Pinwheels are another chocolate covered marshmallow cookie similar to Malamar's, but they're on shelves the entire year and despite being always available, they don't get nearly the attention Malamars do. So the answer to the mystery of why people like Grace Dewey can't buy Malamars all year is the company figures she would probably love them a whole lot less if she could. And they might be right.
Grace Dewey
That is part of the fun. Most definitely part of the fun. You can't get them every day, so it's very special when they do come out. You know, at my age, one month after another just repeats. But as soon as I see that ad that it goes on sale, I know it's fall and it's Malamar season and I have to start collecting. And it's a little sad too, when the warm weather starts coming and there's none to be had by the end of the season.
Willa Paskin
Like, you can tell me the truth, it's okay. But like, by March, are you like, I'm sick of this cookie.
Grace Dewey
I never get sick of them.

Don Martin
I found something as far back as 1883. The Washington, D.C. evening Star says the holiday season of trade seems to begin earlier every year, which sounds very much like the sort of thing people would say now.

Hi, I'm Josh Levine. My podcast the Queen tells the story of Linda Taylor. She was a con artist, a kidnapper, and maybe even a murderer. She was also given the title the Welfare Queen, and her story was used by Ronald Reagan to justify slashing aid to the poor. Now it's time to hear her real story. Over the course of four episodes, you'll find out what was done to Linda Taylor, what she did to others, and what was done in her name.

The great lesson of this for me is that people will come to their own conclusions based on what their prejudices are.
