1 tablespoon cayenne pepper (optional for a hint of spice)
4 pounds of baby back pork ribs
Salt, to taste
Spray inside of a 6-quart slow cooker with cooking spray.
Remove inner skin (membrane) from ribs and place ribs in slow cooker. Discard skin.
Combine BBQ sauce, brown sugar, garlic, Worcestershire sauce and cayenne pepper in a small bowl. Mix well to combine and completely cover with half of the sauce.
Season with a good amount of salt and pepper; cover with lid and cook on low setting for 7-9 hours. Refrigerate remaining sauce to use later.
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 in preheated oven at 400°F for about 10 minutes or until beginning to char and crisp on the edges.
