Directions

1. Mix the adobo marinade, ketchup, vinegar, garlic, sugar, thyme and marjoram in a bowl. Reserve half the sauce, and marinate the ribs in the remaining sauce for over two hours, turning frequently.
2. Heat the oven to 350 degrees F and place the ribs in an oven tray and pour some of the sauce on them. Bake for 1 1/2 hours while basting the ribs with the reserved sauce.
