Guaranteed Goof/

Microwave columnist for the New Haven Register and a radio and TV cooking personality, Kreschollek calls herself ""the Microwhiz,'' based on a process of trial-and-error experimentation. Here is her collected wisdom, in a cookbook that shows good sense both in exploiting the potential and avoiding the dangers of the microwave oven. Kreschollek doesn't miss a microtrick, from an effortless way to get clams open to warming peanut butter for easier spreading. She also knows the oven's limitations, especially when it comes to baking. A few recipes, such as the Chinese stir-fry dishes, still seem more like trouble than convenience, but the wide repertoire of everyday dishes, from baked potatoes to moussaka to roast chicken to stuffed trout, make this a good reference.
