As anyone who’s spent time by a crackling campfire or a barbecue pit can attest, the scent of smoke is unmistakable—and surprisingly mysterious. Smoke clings to clothing but vanishes in the breeze. You see it, but you can’t hold it. It’s fantastic in whiskey and terrible in toast. So what exactly is smoke—and what does it do to our food and drinks? What’s the difference between cold and hot smoked...

If you thought food poisoning was just a matter of the occasional stomach upset from a dodgy shrimp or two, the CDC has some unsettling numbers for you: foodborne bacteria is responsible for at least 48 million cases of illness, more than 130,000 hospitalizations, and 3,000 deaths a year in the U.S. alone. And those numbers aren't going down. But wait: a new fighter has entered the ring! Say hello...

It’s hard to imagine the American restaurant landscape without Thai food: Tom yum and pad see ew are practically household names, and pad thai is the ultimate quarantine comfort food. (It's apparently zombie apocalypse comfort food, too, as shown on the Walking Dead.) According to the Thai Embassy, more than 50 percent of all Thai restaurants abroad are located in the United States and Canada. So...

If you live in the United States, you’re familiar with a curious mathematical ritual that takes place at the end of every restaurant meal—it’s time to tip, with all the stress the process entails. How much should you leave? Who's getting that money? Is it enough? (And will you look like an idiot if you start counting on your fingers?) Unlike many other countries, where people tip by rounding up to...

Cue the dramatic music, it’s quiz time: Can you identify the people behind these catchphrases? “Yum-O!” “Pukka!” “Bam!” “Peace, love, and taco grease!” The answers are below—but if you’ve already caught on, then you’re well aware of how entrenched TV chefs are in mainstream pop culture. But how did a medium where you can’t actually smell or taste the food get so popular? What was the very first fo...

Imagine, for a moment, a world without garlic: garlic-free garlic bread, tzatziki sans Allium sativum, a chili crisp defanged. If this sounds like the makings of a horror story to you, you’re not alone. Garlic consumption in the U.S. has quadrupled since 1980, and people around the world have been enjoying the stuff for thousands of years. But alliums smell like sulfur, and sulfur is something hum...

Over the past century, we've transformed the arid lands of the American west into year-round, well-irrigated agricultural powerhouses. Today, fruits, nuts, and nearly all of our leafy greens are grown in the desert, using water diverted, stored, and supplied at taxpayer expense. This intense irrigation is having an impact: Reservoir levels are dropping, rivers are drying up, and the state of Arizo...

You could call it the Swiss Army knife of the kitchen: bouillon is a handy ingredient, whether it comes as bottled brown gloop, or a cube wrapped up in shiny foil like a tiny present. Today, cooks around the world rely on this secret ingredient to add depth, flavor, and umami to their cooking. It wasn’t always so; like many of today’s packaged shortcuts, condensed bouillon got its start in the 180...

There’s nothing more American than apple pie—or is there? We might prescribe an apple a day and call our largest city the Big Apple, but this legendary fruit originally hails from the mountains of Kazakhstan. This episode, Michael Pollan (something of a legend himself) tells us how apples become so important on the American frontier, and what cider (the alcoholic kind) had to do with it. We talk t...

Morning fog. Gallon-distemper. Busthead. These are all names for alcohol's age-old after-party: the hangover. But, aside from being a physical (and painful) manifestation of regret, what exactly is a hangover? What's happening in our bodies—and specifically in our livers—and can science do anything about it?

To snack or not to snack? And what counts as a snack, anyhow? Plus the great meal vs. snack smackdown: is grazing good, or does eating between meals lead to waistline expansion? We’re asking deep questions about not-so-substantial foods in this crispy, crunchy, and highly craveable episode. Along the way, we uncover snacking’s early connections to pirate’s booty, reveal which of your favorite snac...

Fried, roasted, mashed, steamed: it's hard to imagine life without the crispy, fluffy comfort blanket of potatoes. But until the late 1500s, no one outside the Americas had ever encountered this terrific tuber, and initially Europeans, particularly peasant farmers, didn't trust it at all. Or did they? This episode, we tell the story of the potato's rise to global dominance once it set sail from it...

Saddle up, folks: Today’s episode involves the cowboys' lullabies and meat riots that helped make beef an American birthright. With the help of Joshua Specht, author of Red Meat Republic, we tell the story of how and why the 30 million bison that roamed the Plains were replaced with 30 million cows. You'll never look at a Porterhouse steak—the first cut of beef invented in America—the same way aga...

Consider the lobster roll: tender chunks of lobster bathed in butter or mayo, sandwiched between two slices of a squishy bread roll… Have we caught your attention yet? Lobster is a summertime staple in New England, a fixture on casino and cruise ship buffets, and a steady partner for steak in the classic surf 'n' turf. Today, the American lobster industry is the single most valuable fishery in the...

This episode, Gastropod is bringing you a guest: Science Diction, a bite-sized podcast about words, and the science stories behind them. They answer questions like: what does the word “meme” have to do with evolutionary biology? And why do we call it the Spanish flu when it wasn’t from Spain? Science Diction is doing a series on food words, and this episode is all about Rocky Road. Grab a spoon an...

Cheers! The lively clink of glass on glass is a must for any festive gathering, whether you’re sipping champagne in a flute or lemonade in a tumbler. We rely on glass in the kitchen—for baking perfectly browned pies, preserving jams and pickles, and so much more. But glass wasn’t always so cheap and ubiquitous: to ancient Egyptians and Romans, this was precious stuff—it was high fashion to own a c...

It's the epitome of summertime: there’s nothing like a cold, juicy slice of red watermelon on a swelteringly hot day. But, once upon a time, watermelons were neither red nor sweet—the wild watermelon has white flesh and a bitter taste. This episode, we scour Egyptian tombs, decaying DNA, and ancient literature in search of watermelon's origins. The quest for tasty watermelon continues into modern...

You’ve seen the news: vegetable seeds are selling out. All that quarantine ennui has combined with anxiety about the gaps on supermarket shelves to create a whole new population of city farmers in backyards and windowsills across America. And everyone from the Los Angeles Times to Forbes to CBS has dubbed these brand new beds of beets and broccoli "COVID-19 Victory Gardens." But what war is your p...

We love eating dinner together with friends and extended family, and we miss it! But why does sharing a meal mean so much—and can we ever recreate that on Zoom? As we wait for the dinner parties, cookouts, and potlucks of our post-pandemic future, join us as we explore the science and history of communal dining. Scientist Ayelet Fishbach shares how and why eating together makes us better able to w...

At last, an episode on pizza! But that raises a tricky question: what exactly is pizza? As it turns out, the original pizzas from eighteenth-century Naples looked nothing like a standard slice—they were more like a focaccia, topped with oil, herbs, anchovies, or whatever else was on hand. Even after these first pizzas met the tomato, the dish was a local peculiarity—most Italians thought pizza was...

It's a safe bet that your recent media diet has included the words "wet market," "zoonotic disease," and "pangolin," as experts take a pause from discussing COVID-19's spread and impact to speculate on the virus's origins. This episode, we're digging into the larger story behind those words, that of our relationship to eating wild animals: how and why have our attitudes to wild meat shifted over t...

From stripy fuchsia beets to unicorn doughnuts, the foods available today on grocery store shelves and in cafe displays are more brightly colored than ever. But this hasn't always been the case. This episode of Gastropod, we offer three stories that explore the colors of our cuisine: How did a food fight between Florida and California turn oranges (the fruit) that perfect bright orange (the color)...

You might have heard of Molly Malone, selling cockles from a wheelbarrow in Dublin, or of Mary, Mary, Quite Contrary, with her cockle shells and pretty maids all in a row—but the chances are most Gastropod listeners have never actually tasted a cockle. And, apparently, you're missing out! For the Native American tribes in the Puget Sound, where cockles used to be abundant, they're a treasured trea...

White or whole wheat: while today the question is most frequently asked at the sandwich counter, the debate over the correct answer goes back literally thousands of years. In the past century, though, as white flour and thus white bread became more accessible, the debate became increasingly heated: "Science finds that white bread develops criminals,” reported newspapers in the 1920s, while anti-wh...
