Yes, that's possible. Place the spare ribs on aluminum foil and brush them with the sauce. Close the foil and place everything on a baking tray. Cook it in a preheated oven at 265 °F (130 °C) for three hours. Remove from the oven and carefully open the aluminum foil (steam can escape here). Brush the meat with barbecue sauce and place them side by side on a baking tray. Return to the oven at 430 °F (220 °C) for another 10 minutes until the ribs are crispy.
