Book excerpt: With this new collection of nearly 200 recipes, America's Test Kitchen has slashed the fat and calories (fat by half and calories by a third) of all of your feel-good favorites, thanks to exhaustive testing and fat trimming techniques that work--and we don't mean just cutting portion sizes in half. We even looked at over-the-top restaurant and fast-food dishes like crab Rangoon, meaty lasagna, and cinnamon rolls and revamped those so they no longer have to be once-in-a-while treats.
