Remove the membrane from the backside of each slab.
Cover the ribs liberally with your favorite BBQ seasoning. Let rest on a sheet pan at room temperature for two hours.
Light your coals with a chimney starter. Let burn for 10-15 minutes. Dump into the basket of the Barrel House Cooker. Set the intake to your altitude setting. Set the barrel onto the base, and let the coals burn for another 5-10 minutes with the lid open. Place the H-frame in the barrel.
Find the second bone from the top, and pierce a hook below that point through the meat. Repeat with the other slab.
Hang the ribs on the H-frame. Close the lid and smoke for 2½ to 3 hours, until the meat starts to pull away and show about ½-inch of the bones.
Remove from the smoker. Let rest for 15-30 minutes. Slice and serve.
