Combine the remaining ingredients except for the sauce. Sprinkle the rub mixture over the ribs on all sides. Depending on the size of your ribs you may not end up needing all of the rub.
Seal the foil tightly, transfer to a large baking sheet and place in the oven.
Bake for 2 1/2 hours.
Carefully open the foil.There will be lots of hot liquid accumulated in the bottom of the foil packets!
Remove the ribs from the foil (they might be quite tender, so support them from underneath using large turners or flat wooden paddles and transfer to the baking sheets.
Brush with plenty of sauce and place ribs under the broiler for about 5 minutes or until the sauce has set.
Let rest 10 minutes before slicing. Serve with more sauce for dipping if desired.
