I would highly (highly) recommend anything written by, well the women I call Roger Gray, that's Ruth Rogers and Rose Gray, of London's River Cafe. They have a few books in print and a few more that can be found if diligent. They cook mostly in the Italian idiom, but there's a bit of English in 'em too (they are, after all English).
What I like about them is two things. First, they project a style of eating and cooking, simple, robust, interesting, that I tend to mimic. Second, they have a system they follow, and then just present variations on a theme. Read the books and you will be eating bruschetta a lot more often or seeing what you can do with mozzeralla; your arugula budget increases. It's just very delicious. On top of all that, the books are easy to read and the pictures, food porn. The best thing I can say about the boooks is that regardless of using one of their recipes, I often try to cook
like them. We have well over 1,000 cookbooks in our bungalow, and if I had to (
) rid ourselves of them, I would throw out Roger Gray last.
