Start with 450 g of rind from a loin roast. Cut the rind into smaller pieces, and halve them for easy cooking.
Prepare a pot with 1½ liters of water. Add 1 tbsp. of vinegar to the water and bring it to a boil.
Boil the rind in the vinegar-infused water for 20 minutes. This softens the rind and prepares it to become extra crispy.
After boiling, rinse the rind thoroughly in cold water. This stops the cooking process and removes excess vinegar.
Pat the rind dry carefully with a tea towel to remove all excess moisture. This is crucial to achieving the desired crispiness.
Sprinkle the rind evenly with 1 tbsp. of coarse salt. This adds flavor and helps draw any remaining moisture out of the rind.
Place the salted rind in a preheated airfryer/actifry at 150°C. Cook them in the bowl for 10 minutes to start the crisping process.
Increase the oven temperature to 220°C and continue cooking for an additional 20 minutes. This step ensures the rind becomes golden and crunchy.
If using an actifry, the rind may begin to clump together: stir them gently and separate them using a fork.
Once the cooking is completed, let the crispy pork cracklings drain and cool on a piece of kitchen paper. This absorbs any excess fat and gives you the perfect texture.
