Choose well-marbled pork belly strips. Remove the skin and then cut it into thin strips. Thiner strips are much easier to cook through and absorb the flavors from the marinating better.
Add a tiny pinch of salt, ground pepper, light soy sauce, oyster sauce, the scallion and ginger, and red bean curd sauce. If you don’t want to find red bean curd sauce, skip it and increase the amount of oyster sauce.
The marinated pork belly should be well covered with a plastic wrapper and set aside for at least 4 hours. Or overnight.
Adding Starch
Remove the pork belly ginger and scallion from the surface before frying, as they might be burnt in the deep-frying process.
Add 1/4 cup starch and massage to ensure the thin layer covers the pork belly. I use sweet potato starch, my top choice for deep-fried dishes. But cornstarch or even flour works if it is hard to find this ingredients.
Message for a couple of minutes until the starch becomes sticky and well covered on the pork belly strips.
Double Air-frying
Brush or sprinkle oil on the surface of the crack, and place the pork belly strip in it. Brushing some oil on the surface of the strips, too
Air fry at 320 degrees F for 10 minutes, then flip the pork belly over at 320 degrees F for another 10 minutes. We are using a lower-temperature air frying process to ensure the pork belly is evenly cooked.
Higher the temperature to 390 degrees F, and heat for 3-4 minutes on each side. This will give the pork strips crispy shells.
