Fermenting your own food is very easy, works in your own kitchen and doesn't require a large appliance. In this book on fermentation, author Cathrin Brandes, who offers workshops on how to work with the beneficial bacteria as Krautbraut in Berlin, shows step by step how to do it and how to turn good ingredients into even better products. The old kitchen technique of fermentation, which was used by our grandparents, is not only useful for preserving food. Above all, a diet with fermented foods also ensures healthy intestinal flora and therefore a healthier body.
