Method
- Boil the ribs until partly tender, then drain and set aside.
- Heat the oil. Sauté the onion, garlic, and ginger until fragrant.
- Add the ribs, Fen Yang vinegar, both soy sauces, rice wine if using, brown sugar, oyster sauce, and stock. Bring to a gentle boil and simmer until the ribs are fully tender and the sauce has reduced. Garnish with scallions before serving.
