In a large skillet (or on the grill over medium heat), brown the ribs on each side, a few at a time, in the oil and butter. Return the ribs to the saucepan with the apple juice mixture. Add water, if necessary, to cover them completely. Bring to a boil and simmer gently for about 1 hour and 50 minutes. Monitor carefully the cooking, because while the meat should be tender, it should not fall off the bone.
