Ingredients:
Pork skin 500g
Water, enough to cover the pork skin
Seasonings, as needed
Tools:
Electric pressure cooker
Oven
Air fryer
Instructions:
Cook the pork skin in an electric pressure cooker for 40 minutes.
Remove any excess fat from the pork skin and cut it into small pieces.
Lay the pork skin pieces on a baking tray and bake in the oven with hot air at 90 degrees Celsius for 16 hours (adjust the time and temperature based on your own machine; if you don't have an oven, you can air-dry the pork skin at room temperature for a few days until it becomes completely hard).
Preheat the air fryer to 200 degrees Celsius and air-fry the dried pork skin for 5 minutes (alternatively, you can use the oven or deep-fry it in oil).
Sprinkle some seasonings on the crispy pork skin and it's ready to be enjoyed as a delicious snack or used as an ingredient in other dishes.
