Seasoning a cast-iron skillet is a process that involves creating a layer of polymerized oil on the surface to provide a natural nonstick coating and protect the skillet from rusting. Here's how you can season a cast-iron skillet for the first time:
Preheat the oven: Start by preheating your oven to around 350-400°F (175-200°C).
Clean the skillet: Ensure that your skillet is clean by washing it with hot water and a small amount of mild dish soap. Scrub it with a stiff brush or sponge to remove any debris or residue. Rinse it thoroughly and dry it completely.
Apply a thin layer of oil: Choose an oil with a high smoke point, such as vegetable oil, flaxseed oil, or canola oil. Pour a small amount of oil onto a paper towel or cloth, and use it to rub a thin layer of oil all over the skillet, including the inside, outside, and the handle. Make sure to coat every surface with a thin and even layer of oil.
Remove excess oil: After applying the oil, use a clean paper towel or cloth to remove any excess oil from the skillet. You want to create a very thin layer, as too much oil can lead to a sticky or gummy surface.
Place it in the oven: Once the skillet is oiled, place it upside-down in the preheated oven on the center rack. To catch any potential drips, you can put a sheet of aluminum foil or a baking sheet on the rack below.
Bake the skillet: Let the skillet bake in the oven for about one hour. This process will allow the oil to polymerize and create the nonstick coating.
Cool and repeat if necessary: After an hour, turn off the oven and allow the skillet to cool completely inside the oven. If you want to further enhance the seasoning, you can repeat the process of applying oil and baking for another round.
Using Bacon Grease: Yes, you can use bacon grease to season a cast-iron skillet. Bacon grease can add flavor to the skillet and help create a nice seasoning. The process would be similar to the steps outlined above. After cleaning the skillet, you can use a paper towel or cloth to apply a thin layer of bacon grease all over the skillet, including the cooking surface. Then, proceed with the seasoning process by heating the skillet in the oven as described.
Remember, the key to successful seasoning is to apply a thin and even layer of oil or grease, and to repeat the process multiple times to build up a good seasoning. With regular use and proper maintenance, your cast-iron skillet will develop a durable and natural nonstick surface over time.
