Jamie Oliver did a very good one for starting out cooking: Ministry of Food.
Shows you how to start with a good base and then how to vary it to make other dishes.
From a review on a popular book buying site:
"Like most of the other reviewers here I think this is a great book for everyone. Although it is aimed at people who are reluctant cooks don't let it put you off if you are more experienced. There are plenty of recipes here for you, too. I enjoy cooking and was worried it would be too basic for me, but far from it! Since receiving it on Thursday I have made the smoked mackerel pate and the chicken wrapped in poshy crispy ham, which were quick, easy and delicious. What I particularly like is the way Jamie uses a base, say for stews, rice or porridge and then gives you four alternatives when you have mastered the basics, so there is A LOT of recipes in here. For beginners there are loads of photographs to show you how things should look at each stage of the recipe. I would highly recommend this to anyone. Brilliant!"
