Chinese Pork Rib Tips

Heat a cast iron pan over medium-high heat. Add oil ginger and pork rib tips in that order to the hot pan. Stir-fry ribs until the surface of the ribs turns golden on all sides about 5 minutes.

Pour enough boiling water on top of the ribs so the ribs are just covered with water. Cover with a lid and cook for 10 minutes. Remove lid and keep cooking until the water is almost absorbed 5 to 20 minutes more. Be careful not to burn the ribs. Add rock sugar vinegar and soy sauce. Stir until well combined and cook until sauce thickens 1 to 2 minutes.
