Reseasoned

Reseasoned is a term often used in the context of cooking, specifically referring to cookware, most commonly cast iron skillets or other cast iron items. Reseasoning is the process of applying a thin layer of cooking oil to the surface of the cast iron and then heating it to a high temperature until the oil polymerizes and bonds to the metal. This process creates a non-stick surface and protects the iron from rust.

New cast iron cookware typically comes pre-seasoned by the manufacturer. However, over time, the seasoning can wear off, especially with frequent use, aggressive cleaning, or exposure to acidic foods. When this happens, the cookware may start to stick, look dull, or even show signs of rust. Reseasoning is the solution to restore the cookware's non-stick properties and protective layer.

The process generally involves cleaning the cast iron thoroughly, often down to the bare metal if rust is present. Then, a very thin layer of a high smoke point oil, such as vegetable oil, canola oil, or flaxseed oil, is applied to the entire surface, inside and out. The cookware is then placed in a hot oven, typically between 400-500 degrees Fahrenheit (200-260 degrees Celsius), for about an hour. This cycle is often repeated multiple times to build up a durable seasoning layer. Regular use and proper care, like cleaning with hot water and a soft brush, and drying immediately, help maintain the seasoning.
