Mom's Oven Baked Pork Rib follows a parboil and bake technique that results in a quick, tender barbecued pork rib. I recommend serving over rice to absorb the finger-licking good sauce.
Cut pork spareribs into serving size pieces---1 or 2 ribs each.
Precook the ribs by parboiling in gently boiling water until tender, approximately 25 minutes; drain the water.
Place the ribs in a shallow baking dish; top with sliced onions.
Combine the remaining ingredients, and pour over pork ribs.
Bake at 350 degrees F until brown, approximately 30 minutes. Baste occasionally. If desired, turn ribs half way through baking to brown the other side.
