Notice:

2. The pot must be fully heated when cooking. Put the food in the pan after the oil is hot.
3. Don't use a pan for the first time cooking starchy food.

Problem:
Why is the surface not smooth?
Cast iron pots are made by pouring molten iron into a mold. It is handmade and not polished.
What should I do if the frying pan is rusty?
Clean with a scouring pad and repeat the process instructions.
