The no-mess way to make and/or store burger patties. Simply press one pound of ground meat into each tray and use the patty cutter to divide into either 4 uniform patties or 9 bite-size sliders. Snap on the airtight lid and place in the freezer until your next cook out. Meat freezes and defrosts evenly every time—without any freezer burn. 6-piece set includes two patty tray dividers—one 4-section and one 9-section plus 2 stackable 8¼"-Sq. x 1¼"H plastic trays with storage lids. Trays are freezer, microwave and dishwasher safe.
