If we at Gastropod were asked to name a perfect food, the oyster would be at the top of our list. Oysters are pretty much always our answer to the question of what we'd like to eat this evening—but are they also the answer to the slow-motion disaster of disappearing coastlines worldwide? Join us this episode as we discover how this magical mollusk contains a pearl of hope in the fight to counter rising sea-levels, prevent erosion, and buffer storm surges everywhere from hurricane-hit New Orleans to New York City's flood-prone fringes. But be prepared: you just might join the ranks of the oyster obsessed.

This episode, we've got the exclusive on the preliminary results of the world's largest personalized nutrition experiment. Genetic epidemiologist Tim Spector launched the study, called PREDICT, to answer a simple but important question: do we each respond to different foods differently? And, if so, why? How much of that difference is genetic, how much is due to gut microbes, and how much is due to any one of the dozens of other factors that scientists think affect our metabolic processes? You’ve heard of personalized medicine, will there be such a thing as personalized diets? And should there be? Can teasing out the nuances of how each individual body processes different foods make us all healthier? To find out, we signed ourselves up as study participants, sticking pins in our fingers, weighing our food, and providing fecal samples, all for science—and for you, dear listeners. Listen in now as we take part in this ground-breaking study, discover our own differences, and find out the early results! (Encore episode)

If "Cajun-style" only makes you think of spicy chicken sandwiches and popcorn shrimp, you need to join us in the Big Easy this episode, to meet the real Cajun flavor. Cajun cuisine and its close cousin, Creole, were born out of the unique landscape of the Mississippi River delta, whose bounty was sufficient to support large, complex Indigenous societies, without the need for farming or even social hierarchies, for thousands of years. Europeans were slow to appreciate the wealth of this waterlogged country, but, as waves of French, Spanish, and American colonists and enslaved Africans arrived in Louisiana and the port of New Orleans, they all shaped the food that makes it famous today. But it would take a formerly enslaved woman turned international celebrity chef, a legendary restaurant that's hosted Freedom Riders, U.S. presidents, and Queen B, and a blackened redfish craze to turn Louisiana's flavorsome food into a global trend. Come on down to the bayou this episode, as we catch crawfish and cook up a storm to tell the story of how Cajun and Creole flavors ended up on home-cooking shows, in Disney movies, and at drive-throughs nationwide.

After Dan’s pasta shape, cascatelli, was launched, people everywhere were cooking with it and sending him photos of what they were making. As exciting as that was, he was disappointed that most folks were only making a handful of well-worn dishes with this new shape. So Dan decided to write a cookbook to show the world that there’s so much more you can and should be putting on all your pasta shapes, cascatelli and beyond! There’s only one problem: he’s never written a recipe in his life. In this four-part series, Dan shares the inside story of creating his first cookbook, Anything’s Pastable — from the highs and lows of recipe testing, to a research trip across Italy, to the agonizing decisions over the design of the cover. Listen to this special guest episode of The Sporkful now.

Close your eyes and imagine this: a world without stuffed crust pizza. We know!—but that was the dismal state of the Italian flatbread scene before 1985, when Anthony Mongiello, aka The Big Cheese, came up with an innovation that loaded even more cheese onto pizza, while saving crusts nationwide from the trashcan. It was a multi-million dollar idea, Mongiello was sure—if only he could figure out how to protect his intellectual property and license it. But can you copyright the recipe for stuffing the crust? Could that puffy, cheese-filled rim be trademarked, or the technique for making it qualify as a trade secret? Can you patent a pizza? And did Pizza Hut, which unveiled their own stuffed crust pie in 1995, steal his idea—or does the concept of a cheesy crust belong to humanity as a whole? This episode, we're diving deep into the weird and wonderful world of food IP, via the legendary legal battles to defend Pepperidge Farm's Goldfish, Smucker's Uncrustables, and that futuristic mall treat of the 90s, Dippin' Dots ice cream. Listen in now for the true story of stuffed crust pizza—a story in which creativity, commerce, and lots and lots of cheese collide.

Shoestring, waffle, curly, or thick-cut: however you slice it, nearly everyone loves a deep-fried, golden brown piece of potato. But that's where the agreement ends and the battles begin. While Americans call their fries "French," Belgians claim that they, not the French, invented the perfect fry. Who's right? This episode, we take you right into the heart of the battle that continues to be waged over who owns the fry—who invented it, who perfected it, who loves it the most? And then we take you behind the scenes into another epic fight: the struggle for the perfect fry. Can food scientists create a fry with the ultimate crispy shell and soft inside, one that can stay that way while your delivery driver is stuck in traffic? Plus, the condiment wars: does mayo really have the edge over ketchup? Listen in now to find out! (Encore episode)

In contrast to the abundance of the Arctic, in Antarctica, "once you leave the coast, you're basically heading to the moon." Jason Anthony, who spent several summers on the seventh continent, told us that in this desert of ice and stone (where the largest terrestrial animal is a tiny wingless midge), food isn't just important—it's everything. This episode is packed full of stories of survival at Earth's southernmost points, from Heroic Era expedition chefs whipping up croissants on the ice, to desperate Dorito auctions when supplies run low today. Plus, listen in now for the scoop on how food fueled the race to the South Pole—and determined the ultimate winner and loser.

You may feel like it's cold where you live, but in the Arctic, the average temperature is well below freezing all year round. In winter, it's also pitch black for weeks on end—not an ideal environment for growing food. Still, for thousands of years, people in the Arctic have thrived in a landscape that most outsiders would find fatally inhospitable. This episode, we point our compasses north on a journey to discover how traditional knowledge, ingenuity, and a lot of hard work—combined with genetics and microbes—have allowed the indigenous populations of the far North to not only successfully feed themselves, but also develop a distinctive and remarkable cuisine. Tune in now for the secrets of a dish that feels like Fourth of July fireworks in your mouth, the story of Iceland's second-most famous celebrity (after Björk), and the science behind how to avoid scurvy on an almost vegetable-free diet. Just don't forget your long underwear!

“There’s the faintest soupçon of asparagus and just a flutter of Edam cheese,” says Paul Giamatti in the movie Sideways. Believe it or not, he's describing pinot noir, not quiche. The world of sommeliers, wine lists, and tasting notes is filled with this kind of language, prices seemingly rising in step with the number of bizarre adjectives. It's tempting to dismiss the whole thing as B.S., but listen in: this episode, author Bianca Bosker takes us along on her journey into the history and science behind blind tasting, wine flavor wheels, and the craft of the sommelier. You'll never feel lost in front of a wine list again. (encore)

This week, Gastropod tells the story of two countries and their shared obsession with a plant: Camellia sinensis, otherwise known as the tea bush. The Chinese domesticated tea over thousands of years, but they lost their near monopoly on international trade when a Scottish botanist, disguised as a Chinese nobleman, smuggled it out of China in the 1800s, in order to secure Britain's favorite beverage and prop up its empire for another century. The story involves pirates, ponytails, and hard drugs—and, to help tell the tale, Cynthia and Nicky visit Britain's one and only commercial tea plantation, tucked away in a secret garden on an aristocratic estate on the Cornish coast. While harvesting and processing tea leaves, we learn the difference between green and black tea, as well as which is better for your health. Put the kettle on, and settle in for the science and history of tea! (encore edition)
