Made of specially formulated, high-heat plastic, this unique rack reduces the fat content of cooked bacon by up to 80%. In your microwave, the bacon hangs from the rack and cooks in the air, not in the fat. The fat collects in the tray to keep the interior of your microwave clean. Cook as many slices of bacon as you like; cooking time is approx. 1 minute per slice. Dishwasher safe, for microwave use only.
