The process, often called polymerization, involves heating oil until it bonds molecularly with the iron, creating a slick, protective layer that resists rust and food adhesion. This is distinct from simply heating oil in a pan; successful seasoning demands precise temperature control and sufficient time for the molecules to align and harden evenly across the surface.
Understanding the Chemistry of Cooking Oil and Iron Layer Formation
This process requires dry heat, typically between 400°F and 500°F, to drive off moisture and initiate the bonding process. Canola Oil: Widely available and cost-effective, it produces a solid, smooth seasoning.
A thin, even coat is vital; pooling of oil leads to an uneven finish with sticky spots that compromise non-stick capabilities. Bake for approximately one hour, then allow the skillet to cool completely inside the oven.
