Shape the patties and store them in a single layer in an air tight container in the fridge. For freezing, line a baking dish with parchment and layer the shaped kebab patties on it. Cover the tray with a cling film and pop into the freezer for 4-5 hours until frozen. Then you can transfer the frozen patties into a zip loc bag and store for a month. I thaw them for 2-3 hours on the counter or overnight in the fridge.
