Quickly and easily make uniform, perfectly formed patties with your BigBiteA(R) Grinder (or most other standard #8, #10/12, #22, and #32 electric grinders). As meat passes through the grinder head you can watch the patty well fill; when it's full, slide the tray over and the patty falls out while a second patty starts to form in the adjacent patty well. Includes two trays so you can make 4" diameter or 2A 1/2" diameter, slider-sized patties (both A 3/4" thick). Made from polypropylene, it's durable and easy to clean.
