Prepare the Ribs: Cut the beef ribs along the bones to ensure each piece contains a single bone. Boil the ribs in a large pot of water for 5 minutes, skimming off any foam that arises.
Marinate: Combine rice vinegar, soy sauce, and rice wine in a bowl. Marinate the boiled beef ribs in this mixture at room temperature for 20 minutes.
Fry: Heat oil in a pan until shimmering. Fry the beef ribs until golden brown on all sides, ensuring a crispy exterior.
Simmer: Return the beef ribs to the pot, adding the marinade and broth. Cook until the sauce thickens into a sticky glaze.
Final Touch: Stir in additional rice vinegar for a flavor boost. Garnish with scallion and sesame seeds before serving.
