Review
Bouchon, chef Thomas Keller's bistro cookbook, offers 180-plus recipes from his eponymous restaurants--there are two. Readers perusing the near-prosciutto-size book will be dazzled, first, by its great looks (there are many beautiful photos), then, perhaps, wonder why so many of its typically homey bistro dishes are so fussy to prepare. Why, for example, must the onions for onion soup be caramelized for five hours, or the muscles of a leg of lamb separated so that each can be cooked to an exact, presumably optimal, temperature.
