Rinse the ribs in water and patting dry with a paper towel.
Remove the membrane, which is on the bottom of the ribs.
Coat ribs with rub, and let sit for 10 minutes.
Place ribs on the grill over indirect heat. (Do not place directly over coals.)
Grill on each side for about 30 minutes, on each side.
Place ribs on a sheet of aluminum foil, and sauce both sides with the chipotle apple butter sauce. Wrap the ribs in the foil, cooking an additional 30 minutes to an hour for more tenderness.
Make sure ribs reach an internal temperature of 145 degrees.
