Stuff on Food - Cooks Illustrated is a funny little magazine. It's Bon Appetit meets Consumer Reports, as recipes are tested using different brands of ingredients and with different types of cooking supplies. It also runs some of the lamest reader tips I've ever seen--"tired of spills and splatters damaging your clothes while cooking? don't buy an expensive apron, turn an old oversized dress shirt into a smock!" Uh, thanks for the hint. It's that sort of dumb, but practical information that makes the Sexy Food Nerds of America's Test Kitchen, the companion PBS show, so much fun to watch.
