When you apply a thin layer of canola oil to the preheated surface and heat it beyond its smoke point, the oil molecules break down and re-bond, creating a hardened coating. If the pan has any handles that are prone to heat damage, consider wrapping them in foil or using an oven mitt to protect them.

Line the bottom of the oven with a sheet of aluminum foil to catch any potential drips and simplify cleanup. The process begins with a thorough cleaning of the cast iron to remove any factory oils, debris, or rust.
Maintaining this temperature for approximately one hour allows the oil to polymerize fully, after which the oven is turned off and the pan is left to cool inside. This layer is hydrophobic and provides a non-stick surface, but it is not the same as a Teflon coating.

Using canola oil effectively means respecting this scientific process and avoiding the temptation to skip the heating phase or apply the oil too thickly. It requires ongoing maintenance to sustain, as the seasoning layer can wear off with aggressive cleaning or improper storage.
