This recipe works for one kilogram of pork belly cooked in a 1400W air fryer. The roasting temperature is 200C. If you have a smaller or larger slab of meat, or if your air fryer has a different wattage, you'll have to adjust the roasting time.
Place the pork belly in a deep pan or pot and pour in enough water to cover.
Add the rest of the ingredients and bring to the boil.
Lower the heat, cover and simmer until the pork is tender and the skin is gelatinous (see notes after the recipe).
Scoop out the pork and rest on a rack for 15 minutes.
Transfer the pork belly to the air fryer basket. Position it with the skin side up.
Roast at 200C for seven minutes.
Turn the pork belly on its side and roast at 200C for five minutes.
Turn the pork belly on its other side and roast at 200C for another five minutes.
Reposition the pork belly with the skin side up and roast at 200C for ten minutes.
Check the skin of the pork belly. If it is crisp and sufficiently blistered, take it out of the air fryer. Otherwise, roast longer, still at 200C, checking every two minutes.
Transfer your crispy pork belly to a chopping board, cut into two-inch cubes and serve.
Notes
The cooking liquid will evapororate during cooking but do not be tempted to pour in additional water. That will dilute the flavors.If you're worried that the pork won't cook evenly, turn it on its sides occasionally.
