Preheat oven to 250°F. Remove the membrane from the back of the ribs if the butcher hasn’t already. Season both sides with salt, pepper, smoked paprika, and garlic powder. Wrap tightly in foil and place on a baking sheet. Bake 2½ hours, until tender and nearly falling off the bone.
While the ribs cook, make the gochujang POM sauce. Add all sauce ingredients to a saucepan over medium heat. Simmer 10 minutes, stirring often, until thick and reduced by about one-third. Increase oven to 425°F (or switch to broil). Unwrap ribs and brush generously with half of the glaze. Roast uncovered 30 minutes, until caramelized.
To serve: Slice ribs between bones. Add to a serving platter and top with POM Wonderful® Pomegranate Arils. Garnish with chopped parsley. Serve with the remaining gochujang POM sauce.
