Quickly and easily make uniform perfectly formed patties with your BigBite® 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 2½" diameter slider-sized patties (both ¾" thick). Made from polypropylene it's durable and easy to clean.
