Combine pork belly, water, whole peppercorn, and dried bay leaves in a cooking pot. Cover the pot and let it boil. Adjust heat between low and medium. Continue boiling for 60 minutes.

Remove pork from the pot. Let it cool down. Slice into thin pieces. Note: I usually freeze the pork for 1 ½ hours before slicing it. This method will harden the meat and fat by a bit. It helps prevent the meat from wobbling when sliced.

Combine sliced pork and Knorr Liquid Seasoning. Mix well.

Arrange pork on an air fryer. Set the air fryer to 350F and air fry for 20 minutes or until pork becomes crispy. Note: Make sure to flip the pork slices in the middle of the cooking process. This will ensure that both sides are cooked properly.
