Heat all ingredients (except ribs) in a saucepan over high heat until boiling. Reduce heat, simmer 30-40 minutes, until sauce is thick. Coat ribs front and back with sauce reserving a small amount of sauce. Wrap ribs tightly in foil and bake covered in oven at 275º F for 3 to 4 hours. Remove ribs from foil, smother with more sauce and finish on grill for 2-3 minutes on each side.
