When ribs are tender and falling apart, transfer onto an oven tray (or baking sheet), lined with parchment paper. (Lift them carefully as the meat will be very tender and falling off the bone).
Pour half of the juices from the slow cooker bowl into the remaining sauce. Baste ribs with half of the sauce and broil (grill) in preheated oven at 400°F (220°C) for about 10 minutes or until beginning to char and crisp on the edges.
Serve ribs with remaining sauce.
Enjoy!!!
