I've just dragged out my Stephanie Alexander "The cook's companion" and I have found it to be a great source for recipe ideas. The contents are listed by ingredients so I just look up "Cauliflower" for example & it tells me how to prepare it, when to buy it, what other ingredients compliment it and some recipes which I adapt to Cohen's guidelines. I also waste less because I can find many ways to use that whole cauliflower.
I've noticed there are lots of other cookbooks out now that are listed by fresh ingredients.
