COOK IT.
Preheat your wood pellet grill to 250°F.
Remove any excess fat from the ribs, including the membrane if you choose. You can leave the ribs as is, or like Kara shows us, pinwheel them on skewers, or dice them in 1-inch cubes to make burnt ends.
Coat the ribs with mustard and enough BBQ rub or seasoning to cover them on all sides.
Place the ribs on a grate with a foil pan underneath. Smoke them low and slow to render any tough fat and until they reach an internal temperature of 165-175°F. By now, they should begin to form a bark.
Place the ribs into another aluminum pan along with butter and BBQ sauce. Cover with aluminum foil and place back into the grill. Braise until they reach an internal temperature of 200°F, about an hour.
Remove from the grill, keep covered, wrap in a towel or swaddle, and rest in your microwave or cooler for 1-3 hours.
Enjoy!
