About this listen

 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.

  • From Fountain of Youth to Fruit on the Bottom: How Yoghurt Finally Made it Big in America

    From Fountain of Youth to Fruit on the Bottom: How Yoghurt Finally Made it Big in America
    Nov 18 2025
    Yoghurt is the most diverse section of the dairy case: from Icelandic skyr to creamy Australian, and fruity French Yoplait to full-fat Greek. With something to suit every palate, plus a dose of microbes to support healthy digestion, yoghurt is a staple food in the US, hero of a million smoothies, berry bowls, and snack breaks every day. Which is why it's pretty weird that, until about 50 years ago, most Americans had no idea what it was. This episode, we've got the story of the microbial miracle (and ants?) that gave us yoghurt, as well as the secret connection between those heat-loving bacteria and the evolution of lactose tolerance. Plus, for most of history, yoghurt was wildly popular in large parts of the world—the Middle East, the Balkans, Caucasus, much of Asia, and the Indian subcontinent—and totally unknown elsewhere. Even the promise that yoghurt would cure old age, made by a Nobel prize-winning scientist, couldn't persuade Americans to eat it. So how did yoghurt finally capture the hearts of Americans?

  • Yes, You Really Can Make Food From Thin Air—And We Tried It

    Yes, You Really Can Make Food From Thin Air—And We Tried It
    Nov 4 2025
    Every second of every day, plants on earth do something miraculous: they take the carbon dioxide from air and turn it into food. With very few exceptions, everything we eat starts out that way. But what if we wanted to cut out the middlemen, re-wild all those fields full of wheat and corn, and manufacture dinner directly from the atmosphere ourselves? Scientists began dreaming of turning air into food back into the 1800s, but it's only recently that dream has become a reality—with results that, depending on where you live, you can already taste for yourself. In this episode, we’re exploring the history and science that made this particular sci-fi future real: from a space-age vodka and military-grade yogurt-like substance to surprisingly delicious gas-based butter and bonbons. Join us this episode as we explore the weird science and fascinating history behind this futuristic food, and discover how it might help us save this planet *and* survive on new ones.

  • Pizza Pizza!

    Pizza Pizza!
    Oct 21 2025
    At last, an episode on pizza! But that raises a tricky question: what exactly is pizza? As it turns out, the original pizzas from eighteenth-century Naples looked nothing like a standard slice—they were more like a focaccia, topped with oil, herbs, anchovies, or whatever else was on hand. Even after these first pizzas met the tomato, the dish was a local peculiarity—most Italians thought pizza was gross and weird until just a few decades ago. So how did we get from Neapolitan subsistence snack to today's delivery staple? Listen in this episode as we travel with historian Carol Helstosky, author of Pizza: A Global History, and Francisco Migoya, head chef at Modernist Cuisine, from Italy to New York to Brazil and beyond, to tell the story of how pizza conquered the world. All that, plus the tough questions: is Chicago deep dish really pizza? How about bananas on top? What about (gasp) a donut pizza? (encore episode) Learn more about your ad choices.
