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. Find us online at gastropod.com, follow us on Twitter @gastropodcast, and like us on Facebook at facebook.com/gastropodcast.
