Abstract
Abstract A vessel for simultaneous cooking and stirring of food ingredients in the form of a bowl provided with an electrical heating element and two sets of stirring blades, one set provided adjacent the wall of the bowl and the other set mounted on a central handle, both sets being rotated by means of a motor drive applied to the rim of the bowl. The bowl is elevated to provide space for the insertion of a plate underneath and is provided with a central hole in the bottom which during the course of the cooking operation is covered by a plug secured to the central handle which may be lifted upward, after the cooking operation is complete, to uncover the opening in the bowl through which the contents can then be pushed out by the stirring action of the blades onto the plate.
