Prepare the grill for indirect heat using hickory and charcoal and heat to 250 degrees F.

Place the ribs on a clean cutting board and pull off the membrane, the thin fatty skin that lines the underside of the ribs. Trim the ribs of excess fat and meat.

For the rub: Whisk together 2 tablespoons salt, brown sugar, paprika, chile pepper, cumin and pepper. Rub the beef ribs with the seasoning and place on a sheet tray, cover with plastic wrap, and if time, let marinate in the refrigerator for 8 hours or overnight.

For the glaze: Add the maple syrup, apple juice, brown sugar, vinegar, mustard, chile powder, cayenne, salt and pepper to a medium saucepan and bring to a simmer. Cook until syrupy, about 8 minutes, stirring with a wooden spoon on occasion.

Remove the ribs from the refrigerator. Place the ribs meatier-side-down on the grill away from the coals. Cook the beef 3 hours, adding more coals as needed. Turn and cook until the ribs "bend" and the meat easily separates from the bone using a fork, about 45 minutes more. Brush on the glaze to the ribs and cook for another 5 minutes. Remove and slice into individual ribs.
