Production steps:

1, pigskin is bought home, and the white fat part is removed, leaving only pigskin.

2. Boil the treated pigskin in cold water and take it out. After cooling, clean up the residual fat on the pigskin.

3. Wash the treated pigskin, cut it into small pieces, dry it, put it on oiled paper and dry it in the shade.

4. Put the oil in the pot. When the oil cools, put the fully dried pigskin in, heat it slowly with slow fire, and drain the oil after the pigskin is fully expanded by the oil.

5. Store after cooling, and take it out when needed.
