Cynthia Graber and Nicola Twilley
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.

The Whole Hog
Bacon, bratwurst, bangers, barbecue: these are just a few of the many ways people around the world enjoy feasting on pigs. Of all the domesticated animals humans consume, Sus scrofa domesticus is the most fascinating, the most divisive, and, arguably, the most delicious.
In this in-depth conversation with author and historian Mark Essig, author of the book Lesser Beasts: A Snout-to-Tail History of the Humble Pig, Gastropod discovers the evolutionary source of the pigs’ intelligence (scientists have judged them the cognitive equal of a human three-year-old), and why the animals’ physiology so closely resembles our own. We also uncover the real reason Jews originally eschewed pork, and how pigs were the essential but forgotten weapon, alongside guns and germs, that allowed the Spanish and English to conquer and colonize the Americas. Plus, we read and review Barry Estabrook’s book, Pig Tales: An Omnivore’s Quest for Sustainable Meat, which picks up the porcine tale in the present, where Mark Essig leaves off. From helicopter hunting to manure spraying and more, join us and pig out! Learn more about your ad choices. Visit podcastchoices.com/adchoices

Crunch, Crackle, and Pop
“Sound is the forgotten flavor sense,” says experimental psychologist Charles Spence. In this episode, we discover how manipulating sound can transform our experience of food and drink, making stale potato chips taste fresh, adding the sensation of cream to black coffee, or boosting the savory, peaty notes in whiskey.
Composers have written music to go with feasts and banquets since antiquity—indeed, in at a particularly spectacular dinner hosted by Duke Philip of Burgundy in 1454, twenty-eight musicians were hidden inside an immense pie, beginning to play as the crust was opened. Today, however, most chefs and restaurants fail to consider the sonic aspects of eating and drinking. That’s a mistake, because, as we reveal in this episode, sound can affect how fast we eat, how much we’re prepared to pay for our meal, and even what it tastes like. Learn more about your ad choices.

Field Recordings
Plants that can hear themselves being eaten. Microphone-equipped drones that eavesdrop on sick chickens. Lasers that detect an insect’s wing-beats from dozens of feet away.
In this James Bond-inspired episode of Gastropod, we listen to the soundtrack of farming, decode the meaning hidden in each squawk, moo, and buzz, and learn how we can use that information to improve our food in the future.

The Cocktail Hour
Whether you sip it with friends, chug it before hitting the dance floor, or take it as a post-work pick-me-up, there’s clearly nothing like a cocktail for bracing the spirit. In addition to its peculiar history as a medicinal tonic, plenty of hard science lies behind the perfect cocktail, from the relationship between taste perception and temperature to the all-important decision of whether to shake or stir.
What’s more, according to historian David Wondrich, mixology is “the first legitimate American culinary art”—and one that has since caught on around the world. Raise a glass, and listen in as we discover the cocktail’s historical origins, its etymological connection to a horse’s butt, and its rocky history, post-Prohibition. We also check out an original copy of the world’s first cocktail recipe book at New York City’s bartending mecca, Cocktail Kingdom; take a private cocktail science class with Jared Sadoian of The Hawthorne in Boston; and talk red-hot pokers with culinary scientist Dave Arnold.

Gastropod on Gastropods
Finally, Gastropod is tackling gastropods! In this episode, Cynthia visits one of America’s first and only snail farms.
Though Gastropod is, as regular listeners know, a podcast about the science and history of all things gastronomical, we do share a name with Gastropoda, the taxonomic class that includes slugs and snails. And, as it turns out, the history and science of heliciculture, or snail farming, is completely fascinating. Join Cynthia on a trip to rural Washington State to learn how to raise snails and whether fresh and vacuum-packed taste any less rubbery than canned. Plus, you’ll hear about the earliest evidence for human snail consumption, how the Romans fattened theirs up, and all about the bizarre world of snail sex. Learn more about your ad choices.

Savor Flavor
Why does grape candy taste so fake? What on earth is blue raspberry, anyway? And what is the difference between natural and artificial, at least when it comes to flavor?
Join us as we taste the rainbow on this episode of Gastropod, from artificial flavoring’s public debut at the 1851 Crystal Palace exhibition, to the vanilla-burping yeasts of the future. We’ll experiment with Skittles, discover how invented flavors first appeared in our daily diets, and visit a synthetic biology lab, all in our quest to understand what artificial flavor is, was, and might be. Along the way, we’ll learn what exactly goes into designing the perfect pineapple from one of America’s top flavorists, investigate beaver butts, and discover the taste of an extinct banana.

Say Cheese!
Cheese is the chameleon of the food world, as well as one of its greatest delights. Fresh and light or funky and earthy, creamy and melty or crystalline and crumbly—no other food offers such a variety of flavors and textures.
But cheese is not just a treat for the palate: its discovery changed the course of Western civilization, and, today, cheese rinds are helping scientists conduct cutting-edge research into microbial ecology. In this episode of Gastropod, we investigate cheese in all stinking glory, from ancient Mesopotamia to medieval France, from the origins of cheese factories and Velveeta to the growing artisanal cheese movement in the U.S. Along the way, we search for the answer to a surprisingly complex question: what is cheese? Join us as we bust cheese myths, solve cheese mysteries, and put together the ultimate cheese plate. Learn more about your ad choices. Visit podcastchoices.com/adchoices

No Scrubs: Breeding a Better Bull
In 1900, the average dairy cow in America produced 424 gallons of milk each year. By 2000, that figure had more than quadrupled, to 2,116 gallons. In this episode of Gastropod, we explore the incredible science that transformed the American cow into a milk machine—but we also uncover the disturbing history of prejudice and animal cruelty that accompanied it.
Along the way, we’ll introduce you to the insane logic of the Lifetime Cheese Merit algorithm and the surreal bull trials of the 1920s. This is the untold story behind that most wholesome and quotidian of beverages: milk. Prepare to be horrified and amazed in equal measure. Learn more about your ad choices.

Breakfast of Champions
Breakfast: the most important meal of the day. Or is it? In this episode of Gastropod, we explore the science and history behind the most intentionally designed, the most industrialized, and the most argued about meal of all.
Armed with a healthy dose of caffeine chronopharmacology, we embark on a global breakfast tour that exposes the worldwide dominance of Nutella, as well as the toddler kimchi acclimatization process. Meanwhile, back in the U.S., we trace the American breakfast’s evolution from a humble mash-up of leftover dinner foods to its eighteenth-century explosion into a feast of meats, griddle cakes, eel, and pie—followed swiftly by a national case of indigestion and a granola-fueled backlash. Breakfast has been a battleground ever since: in this episode, we not only explain why, but also serve up the best breakfast contemporary science can provide. Learn more about your ad choices.
