Cleaning burnt food from a cast iron skillet or casserole dish can be challenging, but with the right approach, it's possible to restore it to its original condition. Here's a step-by-step method to clean burnt food from cast iron:
Allow the pan to cool: Before cleaning, ensure that the cast iron skillet or casserole dish has completely cooled down. Working with a hot pan can be dangerous and may cause further damage.
Scrape off loose debris: Using a stiff brush or a plastic scraper, gently scrape off any loose or burnt food particles from the surface of the pan. Be careful not to scratch the seasoning or the cast iron.
Add hot water: Fill the pan with hot water and let it soak for some time. The hot water helps to loosen the burnt-on food, making it easier to remove.
Use a gentle scrub brush: After soaking, use a gentle scrub brush or sponge to scrub away the burnt food. Avoid using harsh abrasive cleaners or metal scouring pads, as they can damage the cast iron's seasoning.
Add salt and scrub: If the burnt food residue is stubborn, you can create a paste by mixing coarse salt and a small amount of water. Apply the paste to the affected areas and scrub gently with a brush or sponge.
Rinse and dry thoroughly: Once the burnt food is removed, rinse the pan with hot water to remove any remaining residue. Avoid using soap, as it can strip away the seasoning. After rinsing, dry the pan completely using a towel or by placing it on low heat on the stovetop for a few minutes.
Re-season the pan: If the cleaning process has affected the seasoning of the cast iron, it's a good idea to re-season it. Apply a thin layer of vegetable oil or melted shortening to the entire surface of the pan, including the handle. Wipe away any excess oil with a paper towel. Then, place the pan in a preheated oven at around 350°F (175°C) for about an hour. This will help restore the protective layer and prevent future sticking.
Remember, regular maintenance and proper seasoning are crucial for keeping cast iron cookware in good condition. Avoid using harsh chemicals, excessive soaking, or abrasive cleaning tools that can damage the seasoning or surface of the cast iron. With proper care, your cast iron skillet or casserole dish can last for generations.
