Ingredients
Oops! Something went wrong. Our team is working on it.
4 teaspoons kosher salt
1 tablespoon freshly ground black pepper
1 teaspoon freshly ground white pepper
1 teaspoon cayenne pepper
½ teaspoon garlic powder
2 tablespoons white vinegar
2 teaspoons Dijon mustard
1 rack St. Louis-style pork spare ribs
Directions
Mix salt, black pepper, white pepper, cayenne, and garlic powder together in a small bowl. Set spice rub aside.
Stir vinegar and Dijon mustard together in a small bowl.
Place ribs on a foil-lined baking sheet. Turn the ribs over so that the meat side is down. Use the tip of a small, sharp knife to make some very shallow slashes every few inches through the membrane that covers the ribs. Poke the knife 3 or 4 times between each rib bone, about 1/4 inch deep.
Brush about 1/2 of the Dijon mustard mixture on top. Sprinkle with about 40% of the spice rub. Turn the rack over and brush on the rest of the mustard and vinegar mixture. Sprinkle on the rest of the rub, reserving 1 or 2 teaspoons in case you want to use it to season the cooked ribs later.
Refrigerate the ribs, uncovered, 4 to 12 hours before baking.
Preheat the oven to 300 degrees F (150 degrees C). Remove ribs from the refrigerator.
Cook in the center of the preheated oven for 1 1/2 hours. Remove from the oven and baste with the pan drippings. Continue to cook until very tender and the tip of a knife slides in very easily, about 1 1/2 hours more.
Remove from the oven, baste again, and let ribs rest for 15 minutes before cutting and serving.
Chef’s Notes
Use a 3 1/2- to 4-pound rack of ribs. You can use a couple slabs of baby back ribs instead if you like.
If you don’t end up using the reserved 1 to 2 teaspoons of spice rub for the ribs, use it for coleslaw or potato salad.
If you have to cook these right away instead of letting them sit for 4 to 12 hours, then go ahead — they will still come out really good.
Serve with my All-American Barbecue Sauce.
