Following on from moondog's "shit cooks" thread - if you were to give a book to an adult who wanted to learn to cook, and it may be the only cookery book they'd own for a while, what would you choose?
Mine - top of head:
Leith's Techniques Bible
Stephanie Alexander: Cook's Companion (but no pictures for reference, which I think can be handy for starting out)
Nigel Slater: Appetite - for getting away from being a slave to recipes
