Abstract

Abstract A mold for forming a hamburger patty comprising upper and lower mold members. The lower mold comprises a flat disc portion of a suitable material such as stainless steel, etc. At the center of the disc, a wooden dowel or post extends upwardly, the dowel or post being annular or any other desired configuration. A half round rib extends annularly around the central dowel or post and spaced therefrom. The top of the mold is annular with a depending wall portion which defines the perimeter of the patty. The upper member has a central hollow post of the same shape as the lower dowel or post but with an internal diameter equal to the outer diameter of the lower post. This permits the upper post to slide over the lower post. The upper member is also provided with a complementary half round rib spaced from the central post and adapted to seat over the lower rib when the mold parts are positioned together. A glob or portion of ground meat is placed on the bottom portion of the mold surrounding the central post. The top member is now pressed down so that the hollow post slides over the lower post. The depending edge of the upper mold will cut the meat and confine a correct portion to form the patty in the mold. The posts will form a central opening and the half round members will form a groove in the patty, which now forms a donut shape.
