The new cast iron pot should be heated in an empty pot on the stove, and then coated with pig skin (or fat pork). Be sure to apply it while heating. When all the pots are finished, burn them for a while. If there is no pigskin, it can also be coated with animal oil (chicken oil, butter, etc.). ). The method is to take a small amount of animal oil, heat it and put it in a pot. After melting, gently shake the cast iron pan to let the oil spread all over the pan, and then burn it. Finally, brush the pan clean. You can't eat the oil in the pot, you can pour it out.
After such treatment, the cast iron pot can be used. If you feel that the pot is not thoroughly brushed, you want to clean up the residual grease. You can add another pot of water, then put in the head of vegetables, roots and the like, boil over high fire, cook for a while, then pour out the water and brush the pot.
