Query: Not for the Novice but Excellent for serious bakers

Since I purchased a bread machine that is completely programmable I began experimenting with Sourdough Breads. My experiments were a mixed success. This book has given me a wealth of information of the bread making process and using sourdough. It has helped me troubleshoot and diagnose my experiments. It is NOT for the faint at heart baker, but if you're serious about sourdough, this is THE book to own!
