I went in a beginners' sourdough-making course. I bought a book and read it cover-to-cover. Then I started making sourdough. Each bake was different, but all were complete disasters. And then I bought Elaine Boddy's book, The Sourdough Whisperer, and my luck changed immediately. With its clear instructions and no-nonsrnse approach, I felt inspired to try again. Immediate success followed. And again. And again. If you want to make delicious sourdough, with no fuss and no tears, BUY THIS BOOK!
