Seasoning a new cast iron skillet is essential to create a non-stick surface and prevent rusting. Fortunately, you can achieve this without using any toxic chemicals. Here's a simple method to season your cast iron skillet using natural ingredients:
Wash the skillet: Start by washing the new skillet with warm water and mild soap to remove any factory coatings or residues. Use a scrub brush or sponge to clean it thoroughly.
Dry the skillet: Pat the skillet dry with a clean towel. To ensure all moisture is gone, you can place it on a low heat stove for a few minutes.
Apply oil: Choose a natural, high-smoke-point oil for seasoning. Some common options include vegetable oil, flaxseed oil, grapeseed oil, or coconut oil. Avoid using oils with low smoke points like olive oil, as they can become sticky.
Coat the skillet: Pour a small amount of the oil onto the cast iron skillet's surface and use a paper towel or cloth to spread it around. Make sure to cover the entire surface, including the handle and exterior.
Remove excess oil: After coating, use a clean paper towel or cloth to wipe off any excess oil. The layer should be thin; otherwise, it may become sticky or uneven during the seasoning process.
Heat the skillet: Place the oiled skillet upside down in an oven set to a relatively high temperature, typically between 375°F (190°C) and 450°F (230°C). Put a baking sheet or aluminum foil on the bottom rack to catch any drips.
Bake the skillet: Let the skillet bake in the oven for about 1 to 1.5 hours. This process allows the oil to polymerize and form a smooth, non-stick surface.
Cooling down: Turn off the oven and allow the skillet to cool inside. Don't remove the skillet until it has reached room temperature, as sudden temperature changes may cause the seasoning to crack.
Repeat the process: To build a robust seasoning, you may want to repeat the oiling and baking process several times. The more you do it, the better the non-stick surface will become.
Remember, the key to a well-seasoned cast iron skillet is regular use and proper maintenance. After each use, clean it gently with warm water and a brush or sponge (no soap required). Dry it thoroughly, and if necessary, apply a thin coat of oil before storing it in a dry place. With time and proper care, your cast iron skillet will become a valuable kitchen tool, naturally seasoned and non-stick.
