In Fermentation, Rachel de Thample shines a light on one of the oldest methods of preserving food, which is just as relevant today, and shows you how to produce delicious and health-boosting ferments in your own kitchen.There are more than 80 simple recipes to make everything from sauerkraut and sourdough, kimchee and kombucha, to pickles and preserves, accompanied by thorough explanations of how the fermenting process works. With little more than yeast and bacteria, salt and time, a whole realm of culinary possibilities opens up. With an introduction by Hugh Fearnley-Whittingstall and plenty of helpful step-by-step photographs, this book will bring the art of fermentation to your kitchen.
