In a small bowl, combine the rub ingredients and mix well. Rub the ribs all over with the mixture, pressing lightly to make sure it adhears, and lay them on a foil-lined baking sheet. Place in the oven and cook for 5 hours.
About 40 minutes before the ribs are done, light a fire in your grill.
While the ribs are roasting, combine the sauce ingredients in a medium saucepan and simmer over low heat for 15 minutes, or until the sauce is slightly thinkened. Remove it from the heat and cover to keep warm.
When the fire has died down and the coals are covered with white ash, cut the ribs into individual ribs and place on the grill. Grill for 5 to 7 minutes per side or until the rub developes a crusty appearance. Brush the ribs with the sauce and cook for 1 minute more, until the sauce forms a glaze. Remove the ribs from the fire and serve with the remaining sauce.
