How to make Pork Cracklings in an Air Fryer

1. Using kitchen scissors, cut pork fat cap into the desired size.  I did 2-inch strips.
2. Place pork in the air fryer and set the air fryer to 390 degrees.
3. Set time for 20 minutes, checking at the 10-minute mark and stirring pork.
4. Add additional 5-minute intervals until the pork is crunchy on the outside (mine took 27 minutes total)
5. Let cool and remove cracklings from the air fryer. 
6. Pour pork fat into a glass jar and allow it to cool before refrigerating.

How to make Pork Cracklings in a slow cooker

1. Remove the fat cap from the freezer and let stand 5-10 minutes
2. Cut fat cap into 1-inch sections
3. Place fat cap and water in the slow cooker and set on high for 8 hours
4. After 8 hours, remove any leftover fat with a slotted spoon and drain the lard into a glass jar.  Place remaining pieces of fat in a skillet with salt and onion.  Cook on high for 5-10 minutes or until brown.
