This was confusing, annoying, and not particularly useful. Interspersed within the alphabetical lists of substitutions were lists of things that were similar, but not necessarily substitutable for one another. There were also the bloody obvious line items: one may substitute Fleur de sel and sea salt. Oh, aye, Becky Sue, because they are virtually the same thing. And there was the inclusion of every possible synonym for a food, listed this unhelpful way- Blackberries: see berries. Never would have thought to look there!The Joy of Cooking's substitution table is far more useful, for my money. As is the Googling of specific questions. I further suspect that this book is geared toward the beginning or timid cook.
