May 31, 2016 Everything Old is Brew Again
Pull up a bar stool and prepare to open both your mind and your palate: it’s time to meet beer before it settled down into the fizzy brown brew we know and love today. The ales in this episode of Gastropod represent the future of flavor, but take their inspiration from the pre-industrial pint. Join us as we meet brewers who are making beer with local herbs, roast chicken, and yeasts scraped off the skin of wild blueberries—and then taste the surprisingly delicious results.

April 19, 2016 Museums and the Mafia: The Secret History of Citrus
A slice of lime in your cocktail, a lunchbox clementine, or a glass of OJ at breakfast: citrus is so common today that most of us have at least one lurking on the kitchen counter or in the back of the fridge. But don’t be fooled: not only were these fruits so precious that they inspired both museums and the Mafia, they are also under attack by an incurable immune disease that is decimating citrus harvests around the world. Join us on a historical and scientific adventure, starting with a visit to the ark of citrus—a magical grove in California that contains hundreds of varieties you’ve never heard of, from the rose-scented yellow goo of a bael fruit to the Pop Rocks-sensation of a caviar lime. You’ll see that lemon you’re about to squeeze in a whole new light.

April 05, 2016 Grand Theft Food
It’s easy to assume that burglars and thieves are always after conventional valuables: cash, jewels, or high-end electronics. But some of the most memorable heists actually involve food. Inspired by Geoff Manaugh’s new book, A Burglar’s Guide to the City, we dive into the ancient history and detective science behind food crime.

March 21, 2016 Caffeine: The World’s Most Popular Drug
A tablespoon of it will kill you, but most of us feel like death without it: we’re talking about caffeine this episode. Inspired by a listener question — does green tea have more or less caffeine than black? and what about yerba mate? — Cynthia and Nicky explore the history and science of the world’s most popular drug. Listen in as we discover the curious effect of birth control pills on how our bodies process it, calculate how much of an edge it gives athletes, and learn what dolphin dissection and the American Constitution have to do with each other, and with caffeine.

March 08, 2016 The Maple Boom
Many people only think of maple syrup at the breakfast table, when they’re facing down a stack of hot, fluffy pancakes or some French toast. They’re missing out. Maple is undergoing a major boom, newly ascendant in beverage aisles, Asian kitchens, and even biomedical research laboratories. In this episode, we visit sugar shacks and talk to the experts to find out why tree sap is so hot right now—and whether it can live up to the hype.

February 23, 2016 First Foods: Learning to Eat
How do we learn to eat? It may seem like an obvious question, but it’s actually quite a complicated process. Who decided that mushed-up vegetables were the perfect first food—and has that always been the case? What makes us like some foods and hate others—and can we change? Join us to discover the back story behind the invention of baby food, as well as the latest science on flavor preferences and tips for how to transform dislikes into likes.

February 09, 2016 The Food of Love
Throughout history, humans have attributed aphrodisiac powers to certain foods, from legendary lover Casanova’s diet of fifty oysters for breakfast to chocolate, the default Valentine’s Day gift for the uninspired. But how did such varying vegetables as asparagus, potatoes, and Peruvian maca acquire this reputation—and do any of them actually deserve it? Join us to find out the history and science behind edible aphrodisiacs in this NSFW episode of Gastropod.

January 26, 2016 The End of the Calorie
For most of us, the calorie is just a number on the back of the packet or on the display at the gym. But what is it, exactly? And how did we end up with this one unit with which to measure our food? Is a calorie the same no matter what type of food it comes from? And is one calorie for you exactly the same as one calorie for me? To find out, we visit the special rooms scientists use to measure how many calories we burn, and the labs where researchers are discovering that the calorie is broken. And we pose the question: If not the calorie, then what?

December 15, 2015 End-Of-Year Feast
Cheese science, cilantro phobia, and fork usage: we’ve covered it all on Gastropod. And, for our special end-of-year episode, we’re bringing you updates on some our favorite stories. Join us to find out what happened next… Ever wondered what happened to those researchers in Colombia who discovered they could grow five times more food by adding specially-bred microbes to the soil? Or what’s new in cheese microbiology? This is your chance to find out! To celebrate the end of 2015, we’ve created a tasting menu to update past episodes. Listen in for news from the front lines of fork etiquette and for the science behind Camembert’s color change from minty-green to today’s white rind. We’ve also included your stories of successful cilantro conversion techniques as well as your suggestions for state dishes—including plenty that we’d never even heard of, from Benedictine sandwiches to Cincinnati chili. There’s even a mezcal-tasting party featuring Cynthia’s mom. And, as we share a toast and head into 2016, we’d love to hear from you. Do you have a question about some aspect of food history or science? Ever wondered why tonka beans are banned in the United States, despite being a popular spice in much of the rest of the world? Maybe your teeth feel weird after eating spinach, and you want to know why—and whether anyone else has the same reaction? Or perhaps you’re curious about how tomatoes, which don’t seem as if they should store particularly well for long boat-rides, succeeded in making the leap from the Americas to become a staple in European cuisine? Send us an email or a voice memo, or leave us a message at +1 310.876.2427, and we’ll see what we can do! Finally, a huge thanks to you, our listeners, for a great year.

November 17, 2015 The Mushroom Underground
They’re a kingdom unto themselves, neither animal, vegetable, nor mineral. They count among their number both the world’s largest organism and millions of microscopic, single-celled creatures. And yet not only have they been an important—and delicious—food source for thousands of years, but they also seem to have powerful medicinal properties. What are these mysterious creatures? Fungi!
