This thread is inspired by the discussion on the Jamie Oliver restaurant empire failure. So the question is, among the cookbooks you own, which do you actually turn to for recipes on a regular basis? For us it's quite limited, but Ottolenghi (2 different books - Jerusalem and another whose title I forget), Nigel Slater (Tender, Kitchen Diaries etc.), and some regional Italian books (by Valentina Harris) get used quite often. For specific recipes, I often just use the internet and surprisingly most of the internet recipes have worked perfectly well. I've also used the Forum's Martin Z's recipes now and again. As for the other manifold cookbooks that my wife owns (of the 'food porn' genre), I think David C is right that we've probably cooked just one or two recipes from them and never gone back.
