After drying the water, put the pork into the pot, otherwise it may spill hot water and burn yourself and others.
Use a clamp or spatula to make the raw pork pieces move in a circular motion from the inside out in the pot.
As time goes on, more and more black grease will appear in the pot. At a certain time, you can pour out the black grease, clean the pot and wipe the water with a paper towel.
Repeat the above steps until the color of lard no longer turns black, indicating that the new iron pot is clean.
In addition to cleaning, the maintenance of new iron pots is also very important. You can dry the new wok with water stains, then dry it with low heat, and then apply a thin layer of vegetable oil with kitchen paper.
