The Slider maker from Jokari is a handy kitchen helper. It makes and stores eighteen (18) mini patties while keeping your hands super clean! Use the two included storage trays with lids to freeze, refrigerate, or microwave you hamburger patties. Using these containers to make your own sliders at home, it"s so easy! Simply place 1 pound of ground meat into one of the 2 included trays and use the patty cutter to cut the meat into 9 evenly sized square mini-burgers. Snap the lid on and freeze your patties until needed or season and cook immediately. Your meat will freeze and defrost evenly and you"ll never again have to form hamburger patties again. Great at parties or for smaller appetites!
