1. Wash the inside, outside and corners of the iron pot with warm water first.

2. After cleaning, dry the outside of the pot with a rag, add half a pot of boiling water to the pot, and boil for five minutes. After pouring out the boiling water, wash the pot repeatedly from the inside out with detergent again, and you can see the water that will not turn black again when cleaning for the second time. After cleaning the pan, dry all the water on the pan with special kitchen paper.

3. Turn on the small fire pot to heat it, then pour in more cooking oil, pick up the pot and shake it, so that the oil can fully wet every part of the pot. Then pour off the excess oil, put the fat pork prepared in advance into the pot for refining, wipe the pot repeatedly, turn off the fire in time when the pot is slightly hot and smoky (to avoid burning the pot and pasting it), wipe it slightly after it is slightly cool, and repeat for 3 times.

4. Wash the pan with warm water, dry the water with kitchen paper, brush a layer of cooking oil in the pan to make the pan form an oil film and let it stand for 12 hour, and the pan is ready.
