  • The Most Dangerous Fruit in America

    The Most Dangerous Fruit in America
    Aug 5 2025
    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? (encore) Learn more about your ad choices. Visit podcastchoices.com/adchoices

  • The Colorful Tale of Mexico's A-maize-ing Grain

    The Colorful Tale of Mexico's A-maize-ing Grain
    Jul 22 2025
    This might sound corny, but the relationship between maize and humanity is essential. We rely on corn—globally, more maize is grown than wheat or rice—and, in turn, corn is utterly dependent on us, to the extent that it's lost the ability to reproduce without our help. But corn's wild ancestor is such an unappetizing weed that, for decades, archaeologists couldn't believe today's juicy cobs were all descended from it. From this unpromising beginning, we've got a story that involves empires, vampires, and generations of women chained to the (literal) grindstone. Pass the popcorn and settle in as we explore the past, present, and future of corn—and the many delicious ways Mesoamericans have invented to get their daily dose of vitamin T(ortilla). Plus: do blue and yellow corn chips actually taste different? And what does it mean for your relationship status if you can't get a tortilla to puff? Learn more about your ad choices.

    Probably not.

  • Feasting With Montezuma: Food and Farming in a Floating City

    Feasting With Montezuma: Food and Farming in a Floating City
    Jun 10 2025
    Five centuries ago, before Spanish conquistadors arrived, what's now Mexico City was the Aztec capital of Tenochtitlan—and it took the European invaders' breath away. It was built on an island threaded with canals; it was one of the largest cities in the world; and the Spanish could hardly believe the sheer volume of food sold in the city's main market, let alone the quantity and variety of dishes enjoyed by the Aztec leader, Montezuma. But how did a city built in a lake—and located in a part of the world without cows, sheep, pigs, or chicken—grow enough to feed quarter of a million people? What does it mean to eat like an Aztec, and can you still do it today? This episode, we're time traveling (and real traveling) to find out! Join us on a trip to taste the flavors of Tenochtitlan, and explore the endangered “floating islands” that fed the city—with a menu that included insect eggs, blue-green algae, and some adorable salamanders that just might hold the secret of eternal youth.

  • Going Bananas: How a Tropical Treat Became the World's Favorite Fruit

    Going Bananas: How a Tropical Treat Became the World's Favorite Fruit
    May 13 2025
    In 1870, a strange fruit arrived on the docks in New Jersey, starting an industry that would change the world. That fruit was a banana, and, although it was a staple food in tropical regions, most Americans had never tried one. Today, a century and a half later, even the most depressing gas station, corner store, or hotel breakfast buffet in the land has bananas on offer. This week, we’re exploring the story of how humans transformed a tiny berry full of tooth-breaking seeds into the soft, yellow, suggestively-shaped fruits we know and love. Listen in now for the funny but tragic story that involves the invention of the cruise ship vacation, a Brazilian beauty and her iconic tutti-frutti hat, and the creation of the first "banana republic."

  • Do We Really Have Beer to Thank for the First Writing and Cities?

    Do We Really Have Beer to Thank for the First Writing and Cities?
    Apr 22 2025
    Humanity's love affair with beer goes *way* back: 5,000 years ago, the civilization that arose in Mesopotamia invented writing, and one of the very first things they wrote about was... beer! But where was beer itself invented? This episode, we've got the story of beer's origins, the debate over whether humanity domesticated grains for brewing or for baking, and why beer was so essential to the smooth functioning of the world's first cities and states. But the story of how we know this—how we can decipher millennia-old drinking songs written in a forgotten language and alphabet, analyze pottery to reconstruct the ingredients list for ancient brews, and even figure out that, for maximum authenticity, we need to drink the resulting beverage through a hollow reed—well, that's perhaps even more fascinating! This week, archaeologist Tate Paulette is our guide as we meet the goddess of beer, sneak a peek at the letters of beer-brewing wives left behind by merchant husbands, and enjoy a time-traveling tasting of an ancient ale, produced with the help of cutting-edge science.
