Sour Grapes: The History and Science of Vinegar
2017-08-28 20:15:23
It's found in almost every home, whether it's destined to dress salads or clean surfaces and kill fruit flies. But, effective as it is at those tasks, most of us struggle to get excited about vinegar. Today, however, a handful of enthusiasts and entrepreneurs are trying to launch a vinegar renaissance—one in which we appreciate ...More →


The Birds and The Bugs
2017-08-15 04:32:08
Chicken is such a mainstay of the contemporary American dinner table that it seems hard to imagine that, just a century ago, it was rare and expensive. But over the course of the 20th century, both chickens and the chicken industry exploded in size. Much of that growth can be attributed to the miraculous properties ...More →


It's Tea Time: Pirates, Polyphenols, and a Proper Cuppa
2017-07-31 19:51:03
This week, Gastropod tells the story of two countries and their shared obsession with a plant: Camellia sinensis, otherwise known as the tea bush. The Chinese domesticated tea over thousands of years, but they lost their near monopoly on international trade when a Scottish botanist, disguised as a Chinese nobleman, smuggled it out of China in ...


Peanuts: Peril and Promise
2017-06-20 01:25:54
Despite their diminutive scale, peanuts play an outsized role in American culture. Peanut butter has long been a mainstay of the American lunchbox, with its sticky, slightly sweet nuttiness flavoring the memories of generation after generation of kids. And it's hard to imagine ballgames without, as the song goes, peanuts and Cracker Jacks (which, of course, also ...


Fake Food
2017-06-06 05:12:18
Hamburgers that turn out to be horse, not beef. Honey sweetened with high-fructose corn syrup. Old, grey olives dipped in copper sulfate solution to make them look fresh and green. Fraudulent foods such as these make up as much as five to ten percent of the offerings on supermarket shelves, according to experts—but which food is ...


Here's Why You Should Care About Southern Food
2017-05-22 14:58:40
The food of the South is one of the most complicated, complex, contradictory cuisines in the U.S. This is the region where a monumental mixing of crops and culinary traditions gave way to one of the most punishing, damaging monocultures in the country; where food born in violence and slavery led to delicious, nutritious dishes. ...


Better Believe It's Butter
2017-05-09 05:58:37
Butter is beautiful: solid golden bars add the perfect flakiness to pastry, give cake a delightfully tender springiness, and melt mouth-wateringly onto toast. But unlike its cousin, cheese—another concentrated, solidified form of milk—we don't tend to think of butter as something that's available in hundreds of varieties, each with a different flavor, color, and texture. ...


Meet Koji, Your New Favorite Fungus
2017-04-24 18:12:03
It's impossible to imagine Japanese meals without soy sauce, or the umami-rich fermented bean paste called miso, or the rice-based spirit known as sake. Which means that Japanese cuisine depends on the one fungus that enables the fermentation of all these delicious foods: koji. Today, American chefs are discovering what Asian cooks have known for centuries, that ...


V is for Vitamin
2017-04-10 14:23:16
They're added to breakfast cereal, bread, and even Pop-Tarts, giving the sweetest, most processed treats a halo of health. Most people pop an extra dose for good measure, perhaps washing it down with fortified milk. But what are vitamins—and how did their discovery make America's processed food revolution possible? On this episode of Gastropod, author ...


Hacking Taste
2017-03-14 06:10:35
Taste is the oldest of our five senses, and yet perhaps the least understood. It's far more complicated than salty versus sweet: new research is dramatically expanding our knowledge of taste, showing that it's intimately connected to obesity, mood, immunity, and more. In this episode, we get into the science of how taste works, why we taste what we do, and ...


Cork Dork: Inside the Weird World of Wine Appreciation
2017-02-28 09:15:03
"There's the faintest soupçon of asparagus and just a flutter of Edam cheese," says Paul Giamatti in the movie Sideways. Believe it or not, he's describing pinot noir, not quiche. The world of sommeliers, wine lists, and tasting notes is filled with this kind of language, prices seemingly rising in step with the number of ...


To Eat or Not to Eat Meat
2017-02-14 11:23:10
With flexitarianism on the rise throughout the developed world, and everyone from Bill Clinton to Beyoncé endorsing the benefits of a vegetarian or vegan diet, it can sometimes seem as though meat is just a bad habit that the majority of us are too weak-willed to kick. But is giving up meat morally superior, healthier, ...


We Heart Chocolate
2017-01-30 17:16:56
In the weeks before Valentine's Day, U.S. consumers will buy nearly 58 million pounds of chocolate. This love affair is not limited to just one day or one country: chocolate has spread from its native home in Central and South America to conquer the world. But today, cacao cultivation is facing a series of wicked problems—ones that threaten to ...


Inventing the Restaurant: From Bone Broth to Michelin
2017-01-16 17:12:12
Early humans may have visited each others' caves for a shared meal, but they wouldn't have expected to be served at their own table, or to choose when and what to eat. But today, restaurants are ubiquitous: there are millions of them worldwide, and the average American eats roughly 200 meals a year in one. So ...

Gettin' Fizzy With It
2016-12-12 17:52:52
'Tis the season for a glass of bubbly—but this episode we're not talking champagne, we're talking seltzer. America is in the throes of a serious seltzer craze, with consumption of the bubbly stuff doubling in only a decade, from 2004 to 2014. But where does seltzer come from, and why is it called "seltzer," rather than simply ...


The Spice Curve: From Pepper to Sriracha with Sarah Lohman
2016-11-29 06:28:51
American food has a reputation for being bland—but, according to historical gastronomist Sarah Lohman, "It's nonsense that Americans don't like spicy food." Lohman is the author of a new book, Eight Flavors: The Untold Story of American Cuisine, which explores the stories behind the flavors that have come to define American cuisine. In this episode, she ...


The Buzz on Honey
2016-11-15 05:17:00
Honey seems like a simple, comforting food, slathered on toast, spooned down to soothe sore throats, and beloved of bears, both plush and real. In reality, this sticky combination of bee spit and evaporated nectar is a powerful and ancient ingredient. For much of history, honey was humanity's main source of sweetness, as well as ...


What is Native American Cuisine?
2016-11-01 05:51:16
Pasta, sushi, tacos, samosas, and pad thai: In the U.S., enthusiastic eaters will likely be able to name traditional dishes from a wide variety of cuisines around the world. But most of us couldn't name a single Native American dish from any one the vast network of tribes, cultures, and cuisines that spread across the U.S. ...


Oysters: History and Science on the Half Shell
2016-10-18 10:12:35
We're living in a golden age for oysters. Just two decades ago, an ostreophile would have thought him or herself lucky to choose among a handful of options; today, in the U.S. alone, hundreds of varieties with exotic names like Moon Shoal, Hama Hama, and Kusshi tempt oyster lovers. What creates all those different flavors and ...


Counting Fish
2016-10-03 22:43:44
This week, we are taking on one of the universe's great mysteries: how many fish are in the sea? If you stop to think about it, it seems almost impossible to figure out how many fish there are—after all, they're basically invisible, not to mention constantly moving. But how else are we to know how ...


Seaweed Special
2016-09-12 23:51:10
Seaweed farming is booming: the global harvest has doubled in the past decade, according to a new report from the United Nations University, and it's now worth more than all the world's lemons and limes. Most of that seaweed ends up in our food, though there is a growing market in seaweed-based cosmetics and drugs. ...


The Salt Wars
2016-08-22 18:09:13
Salt is a magical substance. It reduces bitterness, enhances sweetness, boosts flavor, and preserves perishable foods. Without it, we would die: the human body can't make sodium, but our nerves and muscles don't work without it. It was considered rare until quite recently, so it's hardly surprising that, throughout history, salt has been the engine ...


Kombucha Culture
2016-08-08 14:22:23
If you haven't tasted kombucha yet, you probably will soon. The sour-sweet, fizzy, fermented tea is becoming ubiquitous in trendy cafes, workplaces, and health food stores across America. Where did it come from, and how did it get so popular? And what in the world is the slimy, beige blob that produces it? From German POWs to Lindsey Lohan to a ...

Radiolab Presents: Anna in Somalia
This week, we are presenting a story from NPR foreign correspondent Gregory Warner and his new globe-trotting podcast Rough Translation. Mohammed was having the best six months of his life - working a job he loved, making mixtapes for his sweetheart - when the communist Somali regime perp-walked him out of his own home, and sentenced him to a lifetime of solitary confinement.  With only concrete walls and cockroaches to keep him company, Mohammed felt miserable, alone, despondent.  But then one day, eight months into his sentence, he heard a whisper, a whisper that would open up a portal to - of all places and times - 19th century Russia, and that would teach him how to live and love again.
