Fermentation is the new pickling! So say food fetishists. Chewing the Fat co-hosts Louisa Chu and Monica Eng explore the ancient and bubbling world in this week’s Fermento episode. They talk to FermUp podcaster Branden Byers, author of The Everyday Fermentation Handbook: A Real-Life Guide to Fermenting Food without Losing Your Mind or Your Microbes. And Louisa and Monica invite their WBEZ colleague and reporter Lauren Chooljian to taste fermented veggie kefirs and homemade kraut chi, but Will She Eat It? Plus Monica and Louisa take a factory tour of Lifeway Foods to see how kefir is made, then talk with CEO Julie Smolyansky.
