In a small bowl whisk together the garlic, ginger, salt, white pepper and Chinese Five Spice powder. Reserve 1 teaspoon of the dry rub for the wet basting sauce.
In another bowl whisk together the jam, catsup, soy sauce, Gochujang paste, vinegar and teaspoon of reserved dry rub spices. Set aside.
Keep the membrane on the back of the ribs so they hold together while in the slow cooker. Rub the dry rub on both sides of the ribs.
Coat the inside of a slow cooker with cooking spray and arrange ribs along sides and bottom, meaty side facing down. Cook on High for 4 hours.
Carefully remove ribs from slow cooker and with a sharp knife pull off and remove back membrane on ribs. Place meaty side up on a wire rack in a lined baking sheet sprayed with cooking spray. Brush with sauce and broil 5 minutes. Baste and continue to broil another 5 minutes. Serve with remaining sauce and chopped cilantro as garnish.
Notes
Keep the membrane on the back of the ribs so they hold together while in the slow cooker.
Apple cider, red or white wine vinegar may be substituted for the rice vinegar, but add 1/4 teaspoon of sugar to the sauce mixture as well if substituting.
