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.

How Ketchup Got Thick
Ketchup is the crowd-pleaser of condiments—a ubiquitous accessory on dinner tables throughout the United States, and, increasingly, the world. But this kid-friendly classic actually has its roots in a much funkier food: fermented fish sauce! So how did the salty, pungent, amber-colored seasoning that gives Southeast Asian cuisine its characteristic flavor turn into a thick, red sauce typically found atop hamburgers and French fries? It's a saga that involves the fall of the Roman empire, eighteenth-century fish sauce knock-offs made from green walnuts and vinegar, and the marketing genius of one Henry J. Heinz. Listen in now for that story, plus the 1981 ketchup scandal that shook the Reagan White House, in our love song to ketchup's weird backstory and underrated culinary sophistication.

The Milk of Life
No matter what your diet’s like today, we all likely started life eating the same thing: breast milk, formula milk, or a bit of both. But both of these products aren’t always easy to come by. Breastfeeding can be difficult or impossible for some parents, and formula milk isn’t always safe, affordable, or even available — as we’re seeing in the US, where formula milk is currently 70 percent out-of-stock. This episode, we tell the story of how we got here, and we explore what we should we do to make feeding babies easier in the future. Along the way, we find out what makes human milk—or "white blood," as it perhaps should be known—so unique, as well as why Parisian attitudes to feeding infants in the 1800s made it known as a city with no children. We've also got the story of when formula was first invented, the dirty tricks used to market it, and the competing pressures and changing advice that have swung the pendulum from "breast is best" to formula and back again.

Poultry Power: The Fried Chicken Chronicles (encore)
Juicy, crispy, crunchy...fried chicken is undoubtedly delicious. But it's also complicated, in ways that go far deeper than the science behind that perfect crust. From slavery to entrepreneurship and from yard fowl to Gospel bird, the story of fried chicken is filled with challenging contradictions. Grab a drumstick and listen in.

Guest episode: Montréal by Not Lost
Gastropod is excited to present this guest episode of Not Lost, called Montréal: Voyage Voyage. When both his popular culture podcast and long-term relationship come to an end, journalist Brendan Francis Newnam finds he has the time — and freedom — to pursue his dream: a travel podcast where he goes places and learns about them by getting invited to a stranger’s house for dinner. Not Lost is both a delightful travel escape and an insightful look at people — locals and visitors alike — trying to make sense of a constantly changing world. This episode, Brendan and his friend Danielle seek out the je ne sais quoi of the Québécois. Along the way, they learn about the Quiet Revolution, French-Canadian celebrity mags, and local pastries known as “nun’s farts.” Learn more about your ad choices. Visit podcastchoices.com/adchoices

Reinventing the Eel
Aristotle thought they were born out of mud. A young Sigmund Freud dedicated himself to finding their testicles (spoiler alert, he failed). And a legendary Danish marine biologist spent 18 years and his wife's fortune sailing around the Atlantic Ocean to find their birthplace. The creature that tormented all of these great thinkers? It was the eel, perhaps the most mysterious fish in the world—and one of the most expensive per pound. So why are tiny, transparent, worm-like baby eels worth so much? Why have eels remained so mysterious, despite scientists' best efforts? And how has one pioneering farmer in Maine started raising eels sustainably, despite the species' endangered status? All that this episode, plus a nighttime fishing trip, suitcases full of cash, and a compelling argument that when it comes to the American Thanksgiving dinner plate, we should consider ditching the turkey—and replacing it with eel.

Monsanto or MonSatan? How—and Why—a St. Louis Startup Became a Hated Herbicide Giant
A chemical that kills the plants you don’t want—weeds—and keeps the plants you do—food!—seems kind of like magic. After all, weeds are the bane of farmers' lives, causing tens of billions of dollars in lost yield every year. So why is the world's largest herbicide company, Monsanto, so unpopular that it's been referred to as MonSatan? How harmful are today's herbicides for us humans, and for the environments they're seeping into? And do we need weedkillers to feed the world? In part two of our three-part series on weeds, we take on the big questions around this “bad seed” of the farming world—and the fascinating story behind the scrappy St. Louis startup that hooked the world on herbicides.

The Way the Cookie Crumbles
If you’ve baked up a batch of chocolate chip cookies, enjoyed a nice cup of tea and biscuits, or somehow scarfed a sleeve of Oreos, you will know that cookies—or biscuits, as they were known for most of their existence, and still are in much of the Anglophone world—are one of humanity's greatest inventions. But you probably won't know that they started their illustrious career, more than four thousand years ago, as a kind of beer bouillon cube! This episode, we explore how this food of soldiers and sailors was transformed as it spread all over the world, fueling trade and empire, becoming the world's first industrial food, and shaping culture and language along the way. Featuring cookies as preventative medicine, the biscuit feud that followed the Oreo, and the true story of where the chocolate chip cookie really came from—you'll want to pour yourself a nice tall glass of milk for this one! Or, you know, put on the kettle for a cuppa... Learn more about your ad choices. Visit podcastchoices.com/adchoices

Black Gold: The Future of Food...We Throw Away
For a few weeks in 1987, trash was temporarily headline news: a barge filled with waste that would no longer fit in New York City's overflowing landfills spent months wandering up and down the East Coast with nowhere to dump its smelly, rotting cargo. The trash barge's travels triggered a long overdue public rethink of the wisdom of sending all of our waste to landfills—including food. But fast forward more than thirty years, and food still takes up more space in American landfills than anything else. About 30 to 40 percent of food produced in the US gets thrown away, rather than eaten. What's more, putting all that rotting food inside landfills produces a lot of methane, a powerful greenhouse gas. Our ancestors knew exactly what to do with food waste; the earliest descriptions of composting were written on clay tablets more than 4,000 years ago. So why didn't the GarBarge kick off a composting craze? And why is it so hard for us to keep food waste out of landfills? This episode, Gastropod visits the future of food waste: the high-tech facilities as well as the innovative policies that promise to keep our discarded food out of landfills, keep methane from escaping into the atmosphere, *and* turn those food scraps into something useful. Can a state the size of California really keep 75 percent of its food waste out of landfills, as it has pledged to do by 2025—and what will happen if it does? Listen in for compost blow-dryers, fruit-sticker bingo, and a lot of microbes! Learn more about your ad choices. Visit podcastchoices.com/adchoices

Gum's the Word: A Sticky Story
It’s sticky, it’s breath-freshening, and, according to the FDA, it’s technically food—this episode, we’re chewing on the science and history of gum! As it turns out, humans have been harvesting rubbery things to chew just for the chomp of it for thousands of years. But why? We're joined by anthropologists, archaeologists, gum scientists, and etiquette experts on our journey from the ancient birch tar-chewers of Scandinavia to the invention of modern-day, many-flavored bubblegum. How did an exiled Mexican president, a desperate Staten Island inventor, and a soap-selling runaway help gum go from something the Aztecs thought was only fit for children, the elderly, and prostitutes to a multi-billion dollar industry? Why did one country decide to ban gum altogether? And, with its popularity waning, is the gum-chewing bubble about to burst? Learn more about your ad choices. Visit podcastchoices.com/adchoices
