Got a cheap meat grinder and started grinding my brisket trimmings into 85/15 ground. Salt, fine white pepper, a small splash of worcestershire. I then form them with a cast metal press into 1/3 lb patties and freeze them in between wax paper. They store great, cook evenly, and taste fresher than most gourmet burger patties i've tasted. Always juicy and delicious. Highly recommend self-made frozen patties ????????
