In a saucepan over medium heat, combine the tomato sauce, apple cider vinegar, honey, Worcestershire sauce, mustard, and liquid smoke. Stir well and bring to a simmer. Reduce the heat and let it cook for 15-20 minutes, stirring occasionally.

Prepare the Ribs

Remove the membrane from the back of the ribs. In a small bowl, mix together the brown sugar, paprika, salt, black pepper, garlic powder, onion powder, and cayenne pepper to create the dry rub.

Season the Ribs

Rub the dry rub mixture generously over both sides of the ribs. Let the ribs sit at room temperature for about 30 minutes.

Cook the Ribs

Preheat your grill or oven to 225°F (107°C). Place the ribs on the grill and cook slowly for 3-4 hours, or until the meat is tender and pulls away from the bone. If using an oven, wrap the ribs in foil and bake for the same amount of time.

Apply BBQ Sauce

In the last 30 minutes of cooking, brush the ribs with the prepared BBQ sauce. Allow the sauce to caramelize on the ribs.

Serve

Remove the ribs from the grill or oven, let them rest for a few minutes, then slice and serve with extra BBQ sauce on the side.
