SMOKY OVEN SPARERIBS

Steps:

• Heat oven to 200 degrees. In a mixing bowl, combine the brown sugar, ancho chili powder or paprika, salt, garlic powder, cloves and cinnamon.
• Place each slab of ribs on a piece of foil large enough to fold into a packet. Sprinkle spice rub over the ribs, rubbing in thoroughly on all sides. With the ribs meat-side down, tightly fold the foil to form sealed packets.
• Put a rack on a baking sheet, place packets on the rack and put in oven. Bake for 4 hours, then reduce heat to 175 degrees and bake for 2 more hours, or until a fork easily penetrates the meat.
• Open each packet and pour the accumulated juices into a saucepan, then refold the packets. Bring juices to a simmer over medium heat and reduce by about half, until they cling to a spoon. Remove from the heat and stir in the pimentón, vinegar and vanilla extract.
• Remove ribs from foil, coat with the sauce and serve. The ribs can also be finished for 2 to 3 minutes on an open hot grill or smoky closed one, or under the broiler, then coated with sauce.
