Heat oven to 375°F. Remove ribs from package and place on sheet of heavy-duty aluminum foil large enough to extend 3 to 4 inches beyond each end of ribs. Spread all the sauce over ribs, or save for later.
Spoon 1 tablespoon water over ribs if desired. Wrap foil tightly around ribs.
Place foil-packed ribs in baking pan. Heat 30 mins @ 375°F if ribs are refrigerated, 50 mins if ribs are frozen.
