The Science of Seasoning
Understanding the science behind seasoning can help you better care for your cast iron griddle. Seasoning is the process of polymerizing oil on the surface of the cast iron. Polymerization is a chemical reaction in which small molecules (monomers) combine to form larger molecules (polymers). When oil is heated to a high temperature in the presence of iron, it undergoes polymerization, forming a hard, durable, and non-stick layer. The type of oil you use can affect the quality of the seasoning. Oils with a high smoke point and a high content of unsaturated fatty acids, such as flaxseed oil, tend to polymerize more effectively.
