Set oven at 300 degrees F. Baste ribs with the barbecue sauce. Wrap ribs tightly in plastic wrap. Place wrapped ribs on large sheet of aluminum foil, seam side up. Wrap the plastic-wrapped ribs in the aluminum foil, making an envelope. Place envelope of ribs on a cookie sheet or in shallow pan, seam side up. Place in heated oven and bake for 3 hours. Unwrap and serve. Be very careful as there will be steam build-up inside the package. Serve with coleslaw, baked beans and hush puppies or corn bread.
