Trim the ribs then sprinkle the BBQ rub. Let marinate for 45 minutes to 2 hours.
Light a pit barrel or similar barbecue pit that allows you to hang. Bring the heat to 275 degrees F (135 degrees C) with hardwood charcoal and a chunk of cherry wood.
Hang the ribs on the H-frame. Cook for 3 hours then check. The ribs are ready when tested with a skewer that slides in without resistance. Depending on the meat this may be between 185 and 205 degrees F (85 to 96 degrees C).
