seasoning (cookware)

properties

A seasoned surface is hydrophobic and highly attractive to oils and fats used for cooking. These form a layer that prevents foods, which typically contain water, from touching and cooking onto the hydrophilic metallic cooking surface underneath. These properties are useful when frying, roasting and baking.

Seasoning (cookware) (Wikipedia) Seasoning or curing is the process of coating the surface of cookware with a bioplastic formed from heated fat or oil in order to produce a heat, corrosion, and stick resistant hard coating. It is required for cast-iron cookware and carbon steel, which otherwise rust rapidly in use, but is also used for many other types of cookware, as it helps prevent food sticking.
