Avocado oil, on the other hand, offers a high smoke point and a stable polymerization rate, making it a favorite for building robust layers. With a high smoke point of around 420°F (215°C), it allows for aggressive heat application without the risk of burning the oil before it can polymerize.
Understanding Polymerization: How Oil Chemistry Creates a Durable Seasoning
Seasoning is not a coating of oil; it is a chemical process known as polymerization. Choosing the right fat for seasoning cast iron is the single most important decision for anyone looking to build a durable, non-stick patina.
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. While it may not create the slickest non-stick surface compared to specialized oils, it is incredibly reliable.
