Well, he wrote a fantastic book, called On Food and Cooking: The Science and Lore of the Kitchen. There are no recipes in it - he explains any and all questions you might ask when cooking. Things like: Why does milk curdle? Does searing really seal in the juices? Why are fresh eggs better? How is cheese made?
Why am I so excited? He has a blog! :D
