⅔ c. Apple Cider Vinegar
½ c. (packed) dark brown sugar
6 Tbsp. Gochujang White Balsamic
¼ c. Chipotle Olive Oil
2 racks St. Louis–style pork spareribs (about 4 lb.)
Kosher salt, freshly ground pepper
oil (for grill)
Place a rack in middle of oven and preheat to 350°. Whisk Apple Cider Vinegar, brown sugar, Gochujang White Balsamic, and Chipotle Olive Oil in a medium bowl until sugar is dissolved. Transfer half of sauce to a small bowl and set aside for serving. (half for grilling and half for serving)
Season ribs all over with salt and pepper. Place each rack on a double layer of foil and wrap up. Set on a rimmed baking sheet; bake until very tender but not falling apart, 2½–3 hours. Let cool.
Prepare a grill for medium-high heat; oil grate. Grill ribs, turning several times and beginning to baste with remaining sauce as soon as ribs begin to brown, until charred and coated with a thick layer of glaze and heated through, 8–10 minutes. Transfer ribs to a cutting board and cut between bones into individual ribs. Serve with reserved sauce alongside.
