The process of applying and baking oil onto cast iron grill surfaces creates a polymerized layer. This layer, known as seasoning, prevents rust and provides a non-stick cooking surface. Proper initial seasoning, followed by maintenance, extends the lifespan and enhances the performance of cast iron grill grates.
Seasoning cast iron grill grates is paramount for their longevity and optimal cooking performance. This protective layer prevents oxidation, crucial for outdoor cooking equipment exposed to the elements. Historically, this practice ensured cookware durability and improved food release, minimizing sticking during grilling.
