Cover Held on Kettle.
Much of the flavor and other virtues of meat and vegetables are lost while undergoing the cooking operation, being carried away in the escaping vapor and heat. In a recently invented kettle, a lid is sealed on under pressure. This prevents the escape of steam and facilitates the cooking process. It is claimed that not only is the cooking done in much shorter time, but that foods prepared in this manner have a more delicate flavor. The lid is held in place by means of a lever which is easily manipulated. In order to prevent the possibility of an explosion when the kettle is on the stove, the lid is fitted with automatic safety valve which permits the steam to blow off when the pressure approaches the danger point.
