To wash a seasoned cast iron skillet before using it for the first time, you can follow these steps:
Rinse with hot water: Start by rinsing the skillet with hot water. Avoid using soap at this stage, as it can strip away the seasoning.
Gently scrub with a brush or sponge: Use a stiff brush or sponge to gently scrub away any food particles or residue. Avoid using abrasive cleaners or scouring pads, as they can damage the seasoning.
Dry thoroughly: After washing, dry the skillet completely using a clean cloth or paper towels. Moisture can promote rusting, so ensure the skillet is entirely dry before proceeding.
Apply a thin layer of oil: Once the skillet is dry, apply a thin layer of oil to the entire cooking surface, including the inside and outside. You can use any cooking oil with a high smoke point, such as vegetable oil, canola oil, or flaxseed oil. Ensure that the layer is thin to prevent it from becoming sticky or pooling.
Wipe off excess oil: Use a clean cloth or paper towel to wipe off any excess oil from the skillet. The oil should be present as a thin coating, and there should not be any visible drips or pools.
Heat the skillet: Place the skillet on a stovetop burner or in an oven preheated to a moderate temperature, usually around 300-350°F (150-175°C). Heating the skillet helps to polymerize the oil, creating a smooth and durable seasoning layer.
Let it cool: Allow the skillet to heat for around 10-15 minutes, then turn off the heat and let it cool naturally. This process helps to set the seasoning and make it more effective.
Once you've completed these steps, your seasoned cast iron skillet should be ready for use. Remember to continue maintaining the seasoning by using and caring for the skillet properly after each use.
