COOK IT.
Preheat your pellet grill to 400°F.
Pat ribs dry with a paper towel, then remove the membrane from each. You can do this with a butter knife and a paper towel, or with the Pit Boss Rib Prep Tool.
Coat the ribs lightly and evenly with avocado oil, then generously season with Pit Boss Cowboy Butter Rub on both sides.
Grill the ribs on the bottom rack until an even sear is achieved, flipping and rotating as necessary. Then, remove the ribs and reduce your grill's heat to 300°F.
Place the ribs in a full-size aluminum pan and coat the tops with softened butter. Then, add beef broth to the pan and cover the ribs and pan with plastic wrap and aluminum foil.
Grill ribs in covered pan for 1 hour.
Remove from the grill and let the ribs rest in the covered pan for 30 minutes.
Carve and serve immediately!
