Ingredients

  • ¾ cup light brown sugar
  • ¼ cup smoked paprika
  • 2 tablespoons cayenne pepper
  • 2 tablespoons garlic powder
  • 3 tablespoons kosher salt
  • 2 racks St. Louis-style pork ribs
  • ½ cup unsalted butter

Cooking Instructions

  1. 1.

    Preheat oven to 325°F. Combine brown sugar, paprika, cayenne, garlic powder, and 3 tablespoons salt in a small bowl; set aside 1/4 cup spice mixture.

    5 min

  2. 2.

    Pat ribs dry with paper towels and rub with remaining spice mixture, massaging into crevices. Wrap each rack in a double layer of foil, crimping edges to seal tightly. Place each foil packet on a rimmed baking sheet and bake until meat is fork-tender at the thickest part but not falling off the bone, 2-3 hours. Let cool.

  3. 3.

    Tear open a corner of each foil packet and carefully pour juices from ribs into a large heatproof measuring cup. Let juices settle, then spoon fat from surface and discard.

  4. 4.

    Heat butter in a medium saucepan over medium, stirring often, until it foams, then browns (do not burn), 5-8 minutes. Add juices from ribs and 1/4 cup reserved spice mixture and bring to a simmer. Cook until reduced by one-third, 15-20 minutes. Remove sauce from heat, add vinegar, and season with salt.

    25 min

  5. 5.

    Prepare grill for medium-high heat; oil grate. Remove ribs from foil and grill, basting with sauce and turning occasionally, until charred in spots, 5-7 minutes. Transfer to a cutting board and let rest 10 minutes. Slice between ribs and serve with remaining sauce.
