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.

Your Mystery Date
Allow us to indulge our inner aunties: We’ve set you up on a really hot date this episode—with one of nature’s sweetest fruits, the date! Adored by pleasure-seekers and paleo dieters alike, dates are a Christmas baking standby, and the first bite when breaking fast during Ramadan. These fudgy, caramelly, brown-buttery fruits are so important in their Arab homelands that they're known as the "bread of the desert" and thought to be the tree of life in the Garden of Eden story. We reveal why this episode, plus we've also got the story of how a Native American couple in Nevada may have saved the Medjool date for the world, as well as how California built an Orientalist fantasy around its burgeoning date industry, complete with Wild East shows, hoochie-coochie dances, and camel races. All that, as well as the squidgy, soft, and oh-so-sweet dates you've been missing out on—and why you might want to play the field a little in future, at least when it comes to dates.

The Most Interesting Oil in the World
Here’s a little riddle for you: What’s all around you, but can’t be seen, smelled, or tasted? Hint: It’s in your Oreos, Nutella, instant noodles, dish soap, shampoo, lipstick, potato chips, pizza dough, packaged bread, chocolate bars, ice-cream, and biodiesel. The answer is ... palm oil, the hidden ingredient on just about every aisle of the grocery store. It's the most ubiquitous, most important, most interesting oil that most of us don't really know. But palm oil wasn’t always so big, or so anonymous—in its West African homeland, it’s a fragrant red oil traditionally used in cooking and ceremonies. So how did palm oil go global? What does it have to do with the European colonization of Africa, soap for grimy factory workers, Girl Scout cookies, and Alfred Nobel of Nobel Prize-fame? How has growing demand for all things palm oil driven deforestation and peat fires in Southeast Asia—and what can we do if we want to rethink our destructive palm oil addiction?

Are Plant- and Fungus-Based Meats Really Better than the Real Thing?
Move over, beef: there’s a new burger in town. Plant-based meats are sizzling hot right now; in 2020 alone, the alternative meat industry saw a record $3.1 billion in investment, with 112 new plant-based brands launching in supermarkets. These juicy, savory, chewy fake burgers are a far cry from the dry, weird-tasting veggie patties of the past. This episode, we visit the Impossible Foods labs to swig some of the animal-free molecule that makes their meatless meat bleed, try fungal food start-up Meati's prototype "chicken" cutlet, and speak to the scientists and historians who can help us compare these new fake meats to their predecessors—and to real meat! Can a plant-based sausage roll be considered kosher or halal? Are plant-based meats actually better for you and for the environment? And how might a mysterious protein-powerhouse fungus named Rosita help feed the world? Learn more about your ad choices. Visit podcastchoices.com/adchoices

Balls *and* Brains: The Science and History of Offal
It’s pretty rare to find organ meat on the dinner table in most American households today, but 90 years ago, the earliest editions of The Joy of Cooking contained dozens of recipes for liver, sweetbreads, and even testicles. For much of history, offal (as organ meat is called) was considered the best part of the animal—so what happened? Why are brains banned in the UK and lungs illegal to sell in the US, and why are Scottish haggis-makers up in arms about it? And the question we’re sure you’ve all been pondering: What do testicles taste like?With the help of Jonathan Reisman, author of the new book The Unseen Body: A Doctor's Journey Through the Hidden Wonders of the Human Anatomy, we explore how the vital functions of various animal organs affect their flavor and taste. Jon’s wife, Anna Wexler, also an academic and a writer, joins us to impart the wisdom she’s gained from years as a judge at the World Testicle Cooking Championship (aka Test Fest). We learn about the culinary history of offal from cookbook author Jennifer McLagan, and butcher Sam Garwin comes over to help us prepare up a massive organ meat feast: a Norwegian heart and lung pate (yes, we scored some lung!); a Georgian testicle stew; rabbit, chicken, and beef liver and onions; and breaded, fried lamb brains. Listen to find out which one we liked best, and which ones were just plain offal! (Sorry, we couldn’t resist.) Learn more about your ad choices. Visit podcastchoices.com/adchoices

Trick or Treat: Soul Cakes, Candy Corn, and Sugar Skulls Galore!
If you live in the U.S., chances are, your first hint of fall isn’t a russet-colored leaf landing on the sidewalk—it’s the orange-wrappered candies taking over the aisles of your local grocery and convenience stores. Forget decorative gourds: it’s officially Halloween candy season! But how did a 2,000-year-old Celtic festival marking the sun's death and the beginning of winter morph into a family-friendly sugar-fest? With the help of Heather Cox Richardson and Joanne Freeman, historians and hosts of the Vox Media Podcast Network show Now & Then, we explore the surprisingly recent introduction of trick-or-treating, and the all-American invention of Halloween as the ultimate candy-permissive, religion-free Frankenholiday. Plus, why do so many cultures around the world celebrate deathy things at this time of year—and why do so many of them involve sugar? All this, plus a rigorous candy corn tasting bravely undertaken by your indefatigable hosts! Learn more about your ad choices. Visit podcastchoices.com/adchoices

Buried Treasure: Weeds, Seeds, and Zombies
If you’ve ever engaged in mortal combat with a patch of ragweed, dandelion, or crabgrass in your garden, you might understand the twin emotions of rage and begrudging admiration when it comes to weeds: They. Just. Won’t. Die. When it comes to commercial agriculture, weeds pose a more existential threat—globally, the proportion of our harvest that is lost to weed infiltration is enough to feed millions, and, even with advanced herbicides, weeds cost farmers in North America an estimated $33 billion in lost yield each year. No matter what we throw at them, weeds just seem to get stronger. This episode, we follow a group of scientists along on a 149-year-old quest to see just how long weeds can survive—and, along the way, figure out what we can learn from weeds, what we really ought to thank them for, and what is a weed, anyhow? Listen in now for zombie seeds, a midnight treasure hunt, and the wild ways that weeds have outwitted us for millennia. Learn more about your ad choices. Visit podcastchoices.com/adchoices

The Barrel That Could Save A Forest
Bourbon has to be aged in barrels, by law; whiskey usually spends years in barrels, by custom; and between 20-30 percent of wine spends some time in one. And almost all of those wooden vessels are made from just two kinds of tree: American white oak and French oak. This episode, we tell the story—and try the whiskey—of the distiller and the barrel-maker who, together, are figuring out how to use the huge, elegant, native oak of the Pacific Northwest to create new flavor, and, in the process, restore an ecosystem that has nearly vanished. Along the way, we figure out the science behind how a barrel affects the taste of what you sip, and we trace the trajectory of barrels from their pinnacle, as the go-to container for everything from fish to petroleum, to their current niche status. Finally, we explore why oak became the default wood for barrel-making—and meet the coopers experimenting with different woods, and an entirely new flavor universe for booze.

Tofu for You: Meet the Cult Leader, the Spy, and the Pioneering Woman Chinese Doctor Who Brought Tofu to the West
For a lot of Americans, tofu conjures up images of bland, squishy cubes: a sorry alternative to meat. Even in Asia, where tofu was born, the soybean was initially seen as unappetizing, not to mention flatulence inducing. This episode, we tell the story of how people in what's now northeastern China figured out how to turn this legume of last resort into an array of nutritious, delicious foods, from slippery beancurd skins to silken puddings, and chewy soy crumbles to funky, fermented hairy tofu. Then we introduce the parade of unlikely figures—including Ben Franklin and a 1970s acid casualty who believed he could communicate telepathically with animals—who finally brought this "soybean cheese" to the Western masses. And, finally, we meet the twenty-first century immigrant entrepreneur trying to rebrand tofu from virtuous but boring into something much more delicious and desirable. Listen in now for all that plus Camembert tofu, anarchist zines, and the curious origins of that Thanksgiving favorite, Tofurkey. Learn more about your ad choices. Visit podcastchoices.com/adchoices

The Great Gastropod Pudding Off (encore)
Four bakers, one evening, and one challenge: Who can steam the best spotted dick? On this week’s action-packed episode, Tom Gilliford, Selasi Gbormittah, and Yan Tsou of Great British Bake-Off fame, along with honorary Gastropod member (and Cynthia’s partner) Tim Buntel, compete to see who can master this most classic of British puddings for the first-ever Great Gastropod Pudding Off! But what in the world is spotted dick? “It’s got nostalgia, mystery, horror, and comedy—it’s a perfect British dish,” explained British food designer and jellymonger Sam Bompas, who joined us to judge the competition. Listen in as Tom tries to beat his rival Selasi, Yan revives the flavor combination that robbed her of a Bake Off victory, and Tim tests out his Yankee-style pudding on the Brits. While the four bakers duke it out in the kitchen, we dive into the history and science of British pudding to find out what makes a pudding a pudding, the secret ingredient that will give your pud a lovely light texture, and why anyone would name a dessert “spotted dick.” Learn more about your ad choices.
