Pat the pork belly dry with paper towels.

Score the skin with a sharp knife in a crosshatch pattern, being careful not to cut into the meat.

Rub the sea salt, into the skin and meat.

Preheat the air fryer to 400°F (200°C).

Place the pork belly in the air fryer basket, skin side up.

Cook at 400°F (200°C) for 10 minutes or until the skin is crispy and puffed.

Remove the pork belly from the air fryer and let it rest for a few minutes.

Cut into bite-sized pieces and serve warm.
