Rub mixture all over ribs until well coated. Step 3Evenly distribute butter cubes over ribs, wrap tightly in foil, and place on prepared baking sheet. Bake until very tender, about 2 1/2 hours. Step 4Switch oven to broil, unwrap ribs, and brush all over with barbecue sauce. Place back on baking sheet and broil until sauce starts to caramelize, 5 minutes.
