Query: A Fun, Educational Read

I like the detective/investigation format of the book. The recipes I've tried from it have turned out great, and there are helpful product recommendations interspersed throughout as well. The author draws from some Cook's Illustrated test kitchen results in his detective work, so we get to benefit of CI's research as well as the author's own testing (which he does in his own kitchen). He writes about ingredients or methods that he tried along the way that DIDN'T work, and why, so that we can learn from his trial-and-error without having to go through it ourselves.The reason I give the book 4 stars, and not 5, is that sometimes the writing style is a bit hard to follow, and the general layout of the book is kind of "blah". There are several black and white photographs attempting to show the difference between two recipes that really don't add much to the book at all, the photos are generally too low-quality to discern whatever difference they're trying to show.
