If you have an old cast iron skillet and you want to use it for vegan cooking, there are a few things you can do to ensure it is suitable for your needs. Here are some steps you can take:
Assess the condition: Inspect the skillet for any rust, buildup, or residue. If it's in relatively good condition with no major issues, you may be able to proceed with reseasoning. If there is significant rust or other damage, you may need to strip and reseason the skillet.
Strip the skillet (if necessary): If your skillet has substantial rust or buildup, it's a good idea to strip the old seasoning before reseasoning. You can use methods like oven cleaner, vinegar, or a commercial cast iron cleaner to remove the old seasoning and rust. Follow the instructions provided by the specific product you choose.
Clean the skillet: Once you've stripped the old seasoning, thoroughly clean the skillet with hot water and a stiff brush. Avoid using soap or abrasive cleaners, as they can remove the natural oils from the iron.
Dry the skillet: After cleaning, dry the skillet completely to prevent rust. You can use a towel or place it on the stove over low heat until all moisture evaporates.
Apply a new layer of seasoning: To season your cast iron skillet, apply a thin layer of vegetable oil, such as canola or flaxseed oil, to the entire surface of the skillet, including the handle. Use a paper towel to evenly distribute the oil and then wipe off any excess.
Bake the skillet: Preheat your oven to around 375°F (190°C) and place the skillet upside down on the middle rack. This allows any excess oil to drip off. Place a sheet of aluminum foil or a baking sheet on the bottom rack to catch any drips. Bake the skillet for about an hour, then turn off the oven and let the skillet cool down completely inside the oven.
By following these steps, you should be able to prepare your old cast iron skillet for vegan cooking. Regular maintenance, including proper cleaning and occasional reseasoning, will help keep your skillet in good condition.
