Directions
Using a meat grinder set up according to the manufacturer's directions and with a medium die, grind the meats into a medium bowl. Using your hands, mix the meat until incorporated, then form into six 6-ounce patties. Season both sides liberally with salt and pepper.
Light a grill. Using tongs and paper towels, lightly grease the grill. Cook the burgers, flipping once, until charred and medium rare, 4 to 5 minutes per side. Transfer to a platter, assemble as desired with buns and toppings, and serve.
