Instructions

  1. 1Boil the pork belly
    Strips of pork belly simmering in a pan of water with ginger slices.

    Place premium pork belly strips into a pot with clear water, scallions, ginger, and cooking wine, then boil for 20 minutes before taking them out.

    Tip: Choose pork belly with well-distributed fat and lean meat for the best texture.
  2. 2Remove the boiled pork
    Boiled strips of pork belly being removed from a pot with kitchen tongs.

    Lift the boiled pork belly strips out of the pot using kitchen tongs after simmering for 20 minutes with water, scallion, ginger, and cooking wine.

    Tip: Make sure to remove the meat once the boiling time is complete to prepare it for scoring and seasoning.
  3. 3Score the pork skin
    A knife making parallel cuts across the surface of a boiled pork belly piece on a wooden cutting board.

    Place the boiled pork belly piece on a wooden cutting board and use a knife to score the skin carefully without cutting all the way through.

    Tip: Score evenly to help the marinades and seasonings penetrate deeply into the meat.
  4. 4Add sauces to the pork
    Dark sauce being poured from a glass container onto scored pork belly strips inside a tray.

    Pour light soy sauce, oyster sauce, and barbecue seasoning over the scored pork belly pieces arranged in a baking tray.

    Tip: Pour the sauces evenly over each piece to ensure rich color and flavor during baking.
  5. 5Season and massage the meat
    Seasoning powder being sprinkled over marinated pork belly pieces in a tray.

    Add seasoning powder and massage the sauces and spices thoroughly into all parts of the scored pork belly.

    Tip: Massage vigorously with gloved hands to make sure every section absorbs the marinade.
  6. 6Apply remaining sauce
    A green silicone brush applying sauce evenly over the surface of marinated pork belly strips in a tray.

    Use a brush to evenly coat the marinated pork belly pieces with the remaining sauce mixture before prepping for the foil wrap and salt crust.

    Tip: Ensure all surfaces are coated evenly for a consistent flavor profile.
  7. 7Brush white vinegar on pork skin
    White vinegar being brushed onto the tin foil-wrapped pork belly skin.

    Brush white vinegar evenly over the exposed surface of the tin foil-wrapped pork belly skin.

    Tip: Vinegar helps crisp up the skin during baking.
  8. 8Salt crust and first bake
    A wooden spoon spreading coarse white salt over marinated pork belly strips wrapped in tin foil.

    Wrap the marinated pork belly tightly in tin foil, brush the exposed skin with white vinegar, cover it completely with coarse cooking salt, and place it in the air fryer at 180 degrees for 25 minutes.

    Tip: Ensure the salt layer is applied evenly to help create a crispy crackling skin.
  9. 9Bake in the air fryer
    Air fryer basket containing the salt-crusted pork belly being inserted into the air fryer appliance.

    Place the salt-crusted pork belly into the air fryer and bake at 180 degrees for 25 minutes.

    Tip: Ensure the temperature is stable for even crisping.
  10. 10Crack the salt crust
    Baked salt layer being cracked and broken apart with a wooden spoon.

    Use a spoon to smash and crack open the baked salt layer covering the pork belly.

    Tip: Tap firmly to break the hardened salt crust away easily.
  11. 11Brush vinegar for second bake
    White vinegar being brushed onto the exposed pork skin after removing the tin foil inside the air fryer basket.

    Remove the tin foil and brush white vinegar once more directly onto the exposed pork skin.

    Tip: This second application of vinegar ensures maximum crunchiness.

Frequently Asked Questions

The coarse salt layer draws out residual moisture from the skin during the first air frying cycle and acts as an insulation shield, preventing the skin from burning while allowing the fat underneath to render completely.
Boiling the pork belly with scallions, ginger, and cooking wine for 20 minutes partially cooks the meat, neutralizes any gaminess, and softens the skin so it can be easily scored and seasoned.
Brushing the skin with white vinegar both before and after the salt crust phase alters the surface pH and removes grease, which is essential for creating those iconic crispy bubbles during the high-heat baking process.
