Mix together Barbeque Sauce and orange juice. Lay ribs in a baking pan and pour BBQ mixture over the top. The ribs should be nearly submerged in the BBQ mix.
Cover pan with foil and set oven to 250°F
Option 1: Cook for approx. 3 hrs (depending on amount of meat). Remove from pan and serve. The meat will be juicy and delicious and it should literally fall right off the bone. If you cook them this way they are EXCELLENT but its nearly impossible to eat them with your hands.
Option 2: Cook meat for about 2 hrs, remove from oven and transfer to hot grill. While on grill, continue to brush with BBQ mix from pan. They should only need a few minutes on each side. The BBQ sauce should get a bit crispy, and although the meat isn't quite as tender this way, they will still be quite tasty and much easier to serve and eat.
