The recipes are great, but the first few chapters that cover his journey to making bread, a bit of the science behind it and talking about the less scientific components of what almost sounds like "luck" (Really, just super detailed experimentation and careful repetition once you get the variables right) in the process of getting the perfect rise.
I've got to admit, i'm not a big reader, but there is something about the way Ken put this book together that I really enjoy. Maybe it's that he worked for IBM before becoming a baker and we both think like technical individuals? Maybe it's just good writing and I need to experience more of it? Whatever it is, I'd encourage you to buy the book...i've got no skin in the game, but bread making is great and his methods are slow but fun (My first bread took 18 hours to go through the whole process).
