So Hot Right Now: Why We Love the Chile Pepper
So Hot Right Now: Why We Love the Chile Pepper Aug 18, 2026 2904 Perhaps no other plant is as entwined with pain and pleasure as the chile pepper. But why does it burn—and why on earth do we crave that uncomfortable sensation? How did capsaicin's fungus-fighting, digestion-enhancing, and adrenaline-triggering powers convince early hunter gatherers in South America to fall in love with the chile's tiny berry ancestors, and then European colonists to spread chile

Where There's Smoke, There's...Whiskey, Fish, and Barbecue!
Where There's Smoke, There's...Whiskey, Fish, and Barbecue! Jul 21, 2026 3065 As anyone who’s spent time by a crackling campfire or a barbecue pit can attest, the scent of smoke is unmistakable—and surprisingly mysterious. Smoke clings to clothing but vanishes in the breeze. You see it, but you can’t hold it. It’s fantastic in whiskey and terrible in toast.

One intrepid Gastropod listener wanted to know: why the difference? We’ve got the story of h
Bringing Home the Bacon: From Shakespeare to the Baconator
Bringing Home the Bacon: From Shakespeare to the Baconator Jun 23, 2026 2890 For many Americans, bacon is an essential element of the perfect breakfast—not to mention a welcome addition to everything from cheeseburgers to doughnuts. But bacon hasn't always been beloved. Ancient Egyptians elites looked down on pork, Judaism and Islam banned it entirely, and in Shakespeare’s time, calling someone “bacon brains” was a serious insult. So how did we go from bacon shaming to tod

Feel the Beet: The Most Fascinating Woman You've Never Heard Of May 5, 2026 2692 For those who like its earthy flavor, the humble beet can do a lot for a salad or a soup. But could it help end slavery? In the 1800s, one woman believed it could—and she wasn't just any old woman. This episode, meet Lydia Maria Child, who wrote the first children's periodical magazine, the first New England historical novel, and one of America's first successful self-help books—all before she tur

Along the way: the invention of sliced bread, the science behind Wonder Bread's curious bounce, and a light dusting of eugenics. Will either win

The Trump administration recently issued new dietary guidelines that it says will "revolutionize our nation's food culture." It's a bold claim—but since when has the government been in the business of telling us what to eat in the first place? How does it know how much of each nutrient will keep us healthy, and why are all the di

Even more surprisin
