What did we do before fridges? The process of fermenting foods - to preserve them and make them more digestible and nutritious - is as old as humanity, and gives complex flavours and health benefits. The talk will be about some fermentation basics - why and how - and will cover some vegetables and grains.

This talk is part of an online talk series “Transition to a Better Future" created by Transition Cambridge, with topics ranging from democracy and nature to imagination, water, food, art, and energy. All talks are free, with donations welcome.

This talk series will run online until the end of March, 2021.
