Pork Ribs Glazed with Sofrito (Costillas de Cerdo Glaceadas con Sofrito)

SOFRITO MARINADE: 1 tablespoon annatto oil
1 tablespoon olive oil
2 tablespoons cider vinegar
1/2 cup basic recaito
2 cups tomato sauce
2 tablespoons tomato paste

1 teaspoon black pepper
1 tablespoon guava jelly
1/4 cup coffee liqueur
8 pounds pork ribs (preferably baby back) additional coffee liqueur for basting

Heat the oils in a large skillet. Add the vinegar and saute the recaito over medium heat for 2 minutes. Add the remaining marinade ingredients and cook for 5 more minutes over medium to low heat. Cool the sauce completely. In a bowl, combine the ribs with marinade and let sit for at least 1 hour, or overnight. Preheat the oven to 350 F. Drain the ribs and discard the marinade. Place the meat in a baking pan and bake for 40 minutes. Turn and bake for another 40 minutes, basting with the coffee liqueur every 15 minutes.
