If you want to learn to make delicious sourdough, get this book. It is the only book about this subject that has ever actually resulted in a delicious loaf. I learned so much about how it works, and I have been baking for 40 years. The book is already loaned out and three others have requested it, as the bread is so good. In addition, it is a joy to read, with well written tales about how this bakery came to be, and it has beautiful photographs. This is the best book on bread I have ever owned.
