In a large skillet, heat the vegetable oil. Add the bacon and cook over moderate heat until crisp, about 6 minutes. Using a slotted spoon, transfer the bacon to a medium nonreactive roasting pan. Working in two batches, add the ribs to the skillet and cook over moderately high heat, turning a few times, until richly browned, about 6 minutes per batch. Transfer the ribs to the roasting pan.
