Seasoning a cast-iron skillet typically involves applying a layer of oil and then heating the skillet at a high temperature to polymerize the oil, creating a non-stick coating. While it may be challenging to achieve the same level of heat control on a hot plate compared to a conventional stove, you can still season your cast-iron skillet using the following steps:
Preparing the skillet: Clean the new skillet with hot water and a scrub brush to remove any manufacturing residues. Dry it thoroughly with a towel or heat it on the hot plate for a few minutes to evaporate any remaining moisture.
Applying oil: Use a high-smoke-point oil like vegetable oil, flaxseed oil, or grapeseed oil to season the skillet. Apply a thin, even layer of oil to the entire surface of the skillet, including the inside, outside, and handle. You can use a paper towel or a cloth to apply the oil.
Removing excess oil: After applying the oil, use a clean paper towel to wipe off any excess oil. The skillet should have a thin and even layer of oil on its surface.
Heating the skillet: Place the oiled skillet on the hot plate and set the heat to medium-high. Allow the skillet to heat up gradually to prevent hot spots. If possible, rotate the skillet occasionally to ensure even heating.
Polymerization: Once the skillet reaches a high temperature, let it remain on the hot plate for about 20 to 30 minutes to polymerize the oil. The heat helps bond the oil molecules to the iron surface, creating a durable and non-stick coating.
Cooling and repeating: After the initial seasoning, turn off the hot plate and let the skillet cool down completely. Once it's cool enough to handle, you can repeat the process by applying another thin layer of oil, wiping off excess oil, and heating the skillet again. Multiple seasoning layers can help build a stronger and more resilient coating.
It's important to note that the seasoning process can produce some smoke and odor, so ensure proper ventilation in your cooking area. Additionally, be cautious when handling the hot skillet and using the hot plate.
Regularly cooking with oil in the skillet and proper maintenance, such as avoiding harsh detergents and scrubbing with abrasive materials, will help maintain the seasoning and keep your cast-iron skillet in good condition.
