However, the smoke point is not the only factor; the polymerization temperature is the specific range where the oil transforms into a solid coating. This layer is what gives cast iron its non-stick properties and protects it from rust.
Understanding Specialized Seasoning Oils and Polymerization
When you apply oil to cast iron and heat it, the triglycerides in the oil break down and bond to the metal, forming a hard, plastic-like layer. These fats provide a strong foundation for a non-stick surface that improves with use.
While the internet is saturated with conflicting opinions, the reality is that the best oil for cast iron seasoning depends on the specific goal, whether that is creating a hyper-non-stick surface for daily frying or building a resilient, corrosion-resistant layer for long-term storage. Canola oil has a moderate smoke point of approximately 400°F (204°C), which is sufficient for building a solid polymerized layer.
