Ingredients
- 3 strips pork belly
- 3 slices ginger
- 2 stalks scallions
- 1 tbsp cooking wine
- 1 tbsp light soy sauce
- 1 tbsp oyster sauce
- 1 tbsp BBQ seasoning powder
- 3 tbsp white vinegar
- 1 cup coarse salt
- 1 tsp special seasoning
Instructions
- 1Blanch pork belly with aromatics

Place three strips of raw pork belly into a pan filled with water, ginger, scallions, and cooking wine to eliminate gamey odors before roasting.
Tip: Add ginger, scallions, and cooking wine to effectively remove gamey odors from the pork. - 2Simmer with aromatics

Continue boiling the pork belly strips in the pot with ginger and scallions until the 20-minute cooking time is completed, then take them out.
Tip: Ensure the water maintains a steady boil to thoroughly blanch the meat. - 3Score the pork belly

Take the boiled pork belly and use a knife to make vertical cuts into the surface, being careful not to cut all the way through the bottom.
Tip: Scoring the meat allows marinades and seasonings to penetrate deeply into the layers. - 4Add sauces for flavor

Pour light soy sauce and oyster sauce directly onto the scored pork belly strips to build a savory base flavor.
Tip: Evenly distribute the sauces across the cuts for balanced seasoning. - 5Apply BBQ seasoning and massage

Apply BBQ seasoning powder to the pork belly and use a gloved hand to thoroughly massage the spices into the meat so it absorbs the flavors deeply.
Tip: Massage firmly to ensure the seasoning reaches deep inside the scored cuts. - 6Wrap securely in foil

Wrap the seasoned pork belly strips tightly in aluminum foil, leaving only the top skin exposed, to lock in internal moisture.
Tip: Wrap securely so the juices do not leak out during cooking. - 7Apply First Vinegar Coat

Wrap the seasoned pork belly securely in aluminum foil with only the top skin exposed, then brush a generous layer of white vinegar evenly across the surface to promote crispiness.
Tip: Brushing the skin with vinegar helps achieve an extra crispy texture during roasting. - 8Cover with Salt Crust

Spread a generous layer of coarse salt entirely over the top of the pork belly strips inside the foil containers.
Tip: The salt layer helps retain moisture and draws out oil from the skin, ensuring perfect crispiness. - 9Remove salt crust

Carefully crack and remove the hardened salt crust from the top of the roasted pork belly without damaging the skin underneath.
Tip: Crack the salt layer gently so it comes off cleanly without damaging the crispy skin underneath. - 10Brush with Vinegar Again

After removing the salt crust and foil, brush the pork belly skin with white vinegar one more time before the final roast to ensure blistering.
Tip: This second application of vinegar ensures the skin blisters and turns golden brown.
