Entertaining, heartfelt, impressive. "Happiness multiplies in four days" is not an empty promise. It's quite simple; you don't need much: sourdough and an empty jam jar. You add flour, water, and patience, and soon it starts bubbling. We feed the sourdough, and it teaches us how to bake bread. Delicious breads that anyone can make and everyone enjoys. There is indeed a formula for happiness in sourdough, and this book takes you on a journey to the people who can share this happiness and to the breads that have emerged from this feeling.
