Abstract: A cooking utensil is made of low thermal expansion glass such as Pyrex. The utensil has a bottom bowl, a top lid and a cooking plate. The bottom bowl has partitions defining cooking spaces and a central collection compartment, all of which are integral to the bowl and are made of the same material. A cooking plate rests on the top surfaces of the partitions and has a central through-hole. Food is placed on the plate. A lid covers the bowl and the plate. As the food is cooked, fats drip down through the central hole into the collection compartment. The cooking spaces may also contain food for cooking.
