This is a perfect episode to listen to when you’re baking your own bread. You’ll find answers to questions you always wanted to ask about your sourdough starter, but there was no one to ask. Did my sourdough go bad? How often should I feed it? Here, we also talk about how old sourdough starters are; who actually owns them, and why sourdough cultures are like cities. Tune in and join our conversation with Karl de Smedt, the sourdough librarian from Puratos Sourdough Library in Belgium.
