Gastropod
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.

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

Déjà-Brew: How Coffee Got Bad, Then Worse, and, Finally, Good Again
If you hopped in a time machine for a cup of coffee from a 17th-century London coffeehouse, you would probably be a bit disappointed by their stale, bitter brews. We told you the story of how coffee jumped from its native soil in Africa to achieve near-world domination in Grounds for Revolution, the first episode in our two-part series. This episode, tune in for the story behind how new technologies, over-the-top advertising, and a forgotten female coffee visionary helped coffee go from bad, to a little better, to downright terrible, before reaching today’s Nirvana of coffee choice and quality. After all, why is a recipe with just two ingredients so hard to get just right? For the answer, we explore the science of coffee brewing, roasting, and flavor, and meet the people who shaped humanity’s pursuit of the perfect cup. All that plus Frank Sinatra, unicorn Frappuccinos, and a whole latte more in our fresh-brewed episode. Learn more about your ad choices. Visit podcastchoices.com/adchoices

Grounds for Revolution: the Stimulating Story of How Coffee Shaped the World
About 400 years ago, a dark and mysterious stranger arrived in Europe and sent the jitters—really, shock waves—through society. That newcomer was the coffee bean, and it's hard to overstate its effects on the world. From its early days as a religious aid to its pivotal role in the founding of the London Stock Exchange, the first scientific society, and even one of the earliest forms of social media, this bitter brown beverage has democratized culture and sparked innovation, all while fueling capitalism and inequality. With the help of Gastropod's own founding godfather, Michael Pollan, as well as a crew of all-star historians, coffee growers, botanists, and coffee scientists, this episode we're telling the story of how coffee has changed everything it touched, from the humble workday to the fate of nations. This is the first of a two-part series on coffee, sponsored by Nespresso: listen now, and then come back in two weeks for the scientific secrets behind the perfect cup.

The Fortune Cookie Quest
No dish of General Tso's, chow mein, or beef and broccoli is complete without a fortune cookie at the end. In fact, factories churn out an estimated *three billion* of these folded confections every year, mostly for the U.S. market. So how did fortune cookies become not just a quintessential part of Chinese takeout, but also an American cultural icon? This episode, we crack open the history of the fortune cookie to get at the conflicted origins—or, at the very least, the winning lottery numbers—hidden within. With the help of author Jennifer 8 Lee, we trace the origin of this oracular cookie back in time: from a court case pitting one set of cookie pioneers in San Francisco against their Angeleno rivals, all the way to the tiny town that may have started it all...a town that's (gasp!) not even in China!

Mango Mania: How the American Mango Lost its Flavor—and How it Might Just Get it Back (encore)
Mangoes inspire passion, particularly in India, which is home to hundreds of varieties of the fruit. They are celebrated in Indian music, poetry, and art; they are mentioned in Hindu and Buddhist religious texts as well as the Kama Sutra; and Indian expats will even pay hundreds of dollars for a single, air-freighted box of their favorite variety. But while the average red-skinned mango in the American grocery store is certainly pretty, they're disappointingly bland and crunchy. This episode, we embark on a mango quest to discover how a mango should taste, why the American mango lost its flavor, and how it might just get it back. This is a story that involves a dentist from New Jersey, George W. Bush, and some Harley Davidsons, as well as a full-on mango orgy—so listen in! Learn more about your ad choices.

Guest Episode: Scents and Sensibility
Gastropod is excited to present this guest episode of Outside/In called Scents and Sensibility. Once upon a time, potpourri was a popular way to freshen up a space. Now, for some, it feels a bit like the lava lamp of fragrance: an outdated fad from a bygone decade. Why was potpourri so popular in the 1980’s, and what happened to it? Did the trend dry up, or just evolve? In this episode, Outside/In explores the transformation of potpourri, from the fermented mush of the Victorian era to the perfumed and colorful bag of pine cones of the eighties, and talks to a few of the people still making potpourri today.

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.
