Greenspan knows her stuff, of course, but it's her droll, anecdotal style (readers learn, for example how a chocolate cake got her fired) and her recipe-making expertise that sets the book apart. Precise descriptions of the baked goods--a pound cake, for example, is said to have a "moist, tightly knit crumb"--help readers understand baking anatomy. Equally exact, and reassuring, are her recipe guideposts--she notes, for example, that rubbing butter into the dry ingredients when making a biscuit recipe will result in "pea-size pieces, pieces the size of oatmeal flakes, and pieces the size of everything in between." With recipe variations and enticing color photos, the book will inspire--and inform--baking novices and experts alike. --Arthur Boehm
