Gastropod

Food with a side of science and history. Every other week, co-hosts Cynthia Graber and Nicola Twilley serve up a brand new episode exploring the hidden history and surprising science behind a different food- or farming-related topic, from aquaculture to ancient feasts, from cutlery to chile peppers, and from microbes to Malbec. We interview experts, visit labs, fields, and archaeological digs, and generally have lots of fun while discovering new ways to think about and understand the world through food. Find us online at gastropod.com, follow us on Twitter @gastropodcast, and like us on Facebook at facebook.com/gastropodcast.

What the Shell? Cracking the Lobster's Mysteries
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 country—but it wasn’t always so. This episode, we're cracking the lobster's many mysteries, including how it went from prison fare to fancy food. There's also the question of what lobster eyes have to do with both the International Space Station and the belief in Intelligent Design, plus the rollicking tale of why it took scientists so long to locate the lobster penis—and what makes lobster sex so, well, steamy? Listen in now for the lobster lore you never knew you needed to know!

Guest Episode: Rocky Road with Science Diction
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 and enjoy! We’ll be back in just one week with our regularly scheduled Gastropod episode.

Shatter-Proof: How Glass Took Over the Kitchen—...
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 clear wine goblet in ancient Rome. Later, Venetians so prized their glass know-how that they imprisoned their glassmakers on an island. So how did glass go from fragile and precious tabletop ornament to an oven-ready kitchen workhorse? How did the inventions of a glassmaker in Toledo, Ohio, transform the peanut butter and ketchup industries, as well as put an end to child labor? And are we running out of sand to make glass?

The Most Dangerous Fruit in America
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 times, with the rediscovery of a lost (and legendarily sweet) varietal in South Carolina—and the Nigerian musical secret that might help you pick a ripe one. But the fruit's history has often been the opposite of sweet: watermelons have featured in some of the most ubiquitous anti-Black imagery in U.S. history. So how did the watermelon become the most dangerous—and racist—fruit in America?

Dig for Victory
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 pot of basil fighting? This episode, historian Anastasia Day helps us explore the history of urban gardening movements—and shatter some of the nostalgic myths about those original World War II-era Victory Gardens. One thing is true: in 1943, more than 43 percent of the fresh produce eaten by all Americans came from Victory Gardens. So, can a combination of vegetable patches, community gardens, and urban farms help feed cities today? Or is growing food in the city just a feel-good distraction from the bigger problems in our food system? And does the hype about high-tech vertical farms live up to environmental and economic reality? Listen in as farmers and activists Leah Penniman and Tepfirah Rushdan, food writer Tamar Haspel, and researchers Neil Mattson and Raychel Santo help us dig in to the science on urban agriculture, and harvest some answers—as well as a tomato or two.

Shared Plates: How Eating Together Makes Us Human
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 work together, and evolutionary psychologist Robin Dunbar and archaeologist Brian Hayden demonstrate how it actually made us human—and led to everything from the common cow to the pyramids. Plus we join food writers Nichola Fletcher and Samin Nosrat for the largest in-person banquet of all time, with Parisian waiters on bicycles, as well as the world’s biggest online lasagna party.

Pizza Pizza!
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 gross and weird until just a few decades ago. So how did we get from Neapolitan subsistence snack to today's delivery staple? Listen in this episode as we travel with historian Carol Helstosky, author of Pizza: A Global History, and Francisco Migoya, head chef at Modernist Cuisine, from Italy to New York to Brazil and beyond, to tell the story of how pizza conquered the world. All that, plus the tough questions: is Chicago deep dish really pizza? How about bananas on top? What about (gasp) a donut pizza?

Eating the Wild: Bushmeat, Game, and the Fuzzy ...
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 time? Why is it that deer shot by a hunter in the U.S. is game, but monkey caught in the Democratic Republic of Congo is bushmeat? With the help of Gina Rae La Cerva, author of the new book, Feasting Wild, we explore what we gain and lose by eating wild, from the lost primeval forests of Europe to Robin Hood, and from smoked monkey to bird spit.

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)? Why did US consumers freak out about the food dye Red #2, and what was the impact on our M&Ms? And finally, who invented the blue raspberry? All that, plus one very sexy indigo-hued blossom.

A Tale To Warm The Cockles Of Your Heart
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 treat: meatier, sweeter, and richer-tasting than other shellfish. But they're also disappearing, and no one knows why—or how to save them. This episode, we join the team of intrepid marine biologists and tribal leaders on a mission to restore the cockle, on a journey that involves cockle viagra, a cockle vampire, and some carefully choreographed simultaneous spawning. Listen in now for a story of shellfish science and cultural history that will warm the cockles of your heart—and perhaps inspire the revival of other indigenous foods.

White vs. Wheat: The Food Fight of the Centuries
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-white bread activists at the time claimed that eating too many slices would causing blindness and facial deformity. But whole-wheat bashers had their retorts ready: "Whiteness and purity go hand in hand," proclaimed health writer Dr. Woods Hutchinson. "The whitest possible of white bread" is "not only much more appetizing, but ... more nutritious and more wholesome than any black, brown or brindled staff of life."White vs. wholewheat: this episode, we dive into the world's longest-running, highest-stakes food fight. Along the way: the invention of sliced bread, the science behind Wonder Bread's curious bounce, and a light dusting of eugenics. Listen in now as Aaron Bobrow-Strain, author of White Bread: A Social History of the Store-bought Loaf, unpacks the anxieties and values underlying the bread wars, while wheat breeder Steve Jones introduces us to the "approachable" loaf that he hopes will win the battle for once and for all.

Licorice: A Dark and Salty Stranger
Licorice is a polarizing candy: there are those who pick out the black jelly beans, those who think Twizzlers are better than Red Vines, and those who won't travel without a supply of salty dark lozenges. The dark and chewy treat begins life as a plant root that is more than fifty times as sweet as sugar. This episode, we tell the story of how a traditional remedy become England's first branded candy, and we get to the bottom of a medical mystery (licorice poisoning!) in a tale that involves both Tutankhamun and Henry VIII.
