The Smitten Kitchen Cookbook, Deb Perelman. Usually cookbooks don't make the "books I read" list, but this one is full of well-written (and really funny) prose. The photos are gorgeous and these recipes haven't let me down yet.
+ I learned to cook many recipes from this Cookbook! Hmm, wonder what happened to it? Betty Crocker's Cookbook (originally called Betty Crocker’s Picture Cook Book) by Betty Crocker – approx. 65 million copies
