In many parts of the world, especially in regions with limited growing seasons and long winters, people preserve vegetables through fermentation. Join Sandor Ellix Katz, a fermentation revivalist, for a virtual discussion about the illustrious history of fermented vegetables, the science behind it and how simple it is to ferment vegetables at home.  Wild Fermentation and The Art of Fermentation, Katz's books, and the hundreds of fermentation workshops he has taught around the world have helped to catalyze a broad revival of the fermentation arts.
