I had always heard that pork and beef was a good meat combo for burgers but only recently tried it. This is my own blend of meats and spices.
Clay's Beef and Pork Burgers
1 1/2lb ground beef (at least 85/15 mix)
1lb ground pork
1/3c Italian seasoned breadcrumbs
1 clove garlic
1/4tsp black pepper
2T Worcestershire Sauce
1/2T Onion Powder
2T Hickory Smoke Allegro Marinade
1tsp white cooking wine.
Mix all ingredients together and let set for at least an hour before cooking. Grill and enjoy! Goes great with the St. Louis Style BBQ.
