Curing, also known as seasoning, a cast iron skillet is the process of creating a natural, non-stick cooking surface and protecting the skillet from rust. Here's a step-by-step guide on how to cure a cast iron skillet:
Note: If you have a new cast iron skillet, it may come pre-seasoned from the factory. In that case, you can skip the initial seasoning and jump straight to maintaining the skillet.
What you'll need:
- Cast iron skillet
- Cooking oil (preferably vegetable oil, flaxseed oil, or canola oil)
- Paper towels or a clean cloth
- Aluminum foil (optional)
Step-by-step process:
Clean the skillet: If the skillet is new, wash it with warm, soapy water to remove any residue from the manufacturing process. If it's an old skillet or one that you've used before, make sure to clean it thoroughly with hot water and a brush, avoiding soap, as soap can strip away the seasoning.
Dry it completely: After washing, dry the skillet thoroughly with a towel or by placing it on a stove over low heat for a few minutes.
Preheat the oven: Preheat your oven to about 350°F (175°C) or slightly higher.
Apply oil: Pour a small amount of your chosen cooking oil into the skillet. Use a paper towel or a clean cloth to spread the oil evenly across the entire surface of the skillet, including the outside and the handle.
Remove excess oil: After coating the skillet with oil, use a clean paper towel or cloth to remove any excess oil. The skillet should have a thin, even layer of oil.
Place the skillet upside down: To avoid pooling of oil, place a piece of aluminum foil or a baking sheet on the oven rack below to catch any drips. Then, place the oiled skillet upside down on the oven rack.
Bake the skillet: Let the skillet bake in the preheated oven for about 1 to 1.5 hours. The heat allows the oil to polymerize, creating a natural non-stick coating.
Cool the skillet: Turn off the oven and let the skillet cool completely in the oven before removing it. Be cautious when handling the skillet, as it will be hot.
Repeat the process (optional): If your skillet is new or the seasoning is not as strong as you'd like, you can repeat the process of oiling and baking to build up a more robust seasoning.
Maintaining the seasoning:
To maintain the seasoning on your cast iron skillet, follow these guidelines:
- After each use, clean the skillet with hot water and a brush, avoiding soap.
- Dry the skillet thoroughly to prevent rusting.
- Apply a thin layer of cooking oil to the skillet after each use to replenish the seasoning and protect it from moisture.
By properly seasoning and maintaining your cast iron skillet, it will become an essential kitchen tool that lasts for generations.
