What does seasoning the pan mean?

Seasoning a pan refers to the process of treating a cookware surface, typically cast iron or carbon steel, to create a natural, non-stick coating. This is achieved by applying a thin layer of oil and heating the pan, which allows the oil to polymerize and bond to the metal. Proper seasoning enhances the pan's performance, prevents rust, and improves the flavor of food cooked in it. Regular maintenance of the seasoning layer is important for optimal cooking results.
