how long and what temp to cook pork ribs
Spare ribs and pork shoulder are both cooked in an oven at the same temperature(~225F) for me. The difference is time. A pork shoulder takes at least 8 hours but usually around 12 hours to give good pulled pork. Ribs are closer to 3-4 hours for the meat to get tender but not so tender that they fall off the bone.
