Abstract: A baking device especially for baking potatoes in a microwave oven comprises a molded microwave transparent plastic ring having integral generally wedge-shaped but thin upstanding blades spaced about its circumference. A flange on the ring provides a handle for lifting the device. The broad opposing surfaces of each blade merge at relatively thin, sharp edges for penetrating a potato but the apex of each blade is rounded for safety. A moisture ventilation slot extends through the blade vertically between its apex and the base. The slot terminates below a stop flange to ensure the escape of moisture from a potato as it cooks. The blades are inclined inwardly from the vertical to prevent tipping the ring when a potato is pushed onto a blade.
