Frequently Asked Questions - Cast Iron Cookware
General Cast Iron Cookware Questions
Is Cast Iron the Safest Cookware?
Cast iron is generally considered safe for cooking, provided it is used correctly and maintained properly. One of the primary benefits is that it does not leach harmful chemicals into food, unlike some non-stick coatings which can degrade over time and release toxic substances. Additionally, cooking with cast iron can add a small amount of iron to your diet, which can be beneficial, especially for those with iron deficiencies. However, it's important to avoid cooking highly acidic foods in cast iron for prolonged periods, as this can lead to metal leaching and damage to the seasoning.
Can Cast Iron Cookware Be Used on Glass Top Stoves?
Yes, cast iron cookware can be used on glass top stoves, but with caution. Due to its heavy weight and rough texture, cast iron can potentially scratch or damage the glass surface. To prevent this, always lift the cookware when moving it, rather than sliding it across the stove. Ensure the bottom of the cookware is clean and smooth before placing it on the glass top. Additionally, because cast iron retains heat very well, be mindful of the heat settings to avoid overheating the glass surface, which can cause it to crack.
How to Cure Cast Iron Cookware
Curing, or seasoning, cast iron cookware involves creating a protective layer of oil that helps prevent rust and provides a natural non-stick surface. Here are the steps to cure cast iron cookware:
-
Clean the Cookware: Wash the cast iron with warm water and mild soap to remove any dust or residue from the manufacturing process. Rinse and dry thoroughly.
-
Apply Oil: Rub a thin layer of cooking oil (such as vegetable oil, canola oil, or flaxseed oil) all over the surface of the cookware, including the inside, outside, and handle.
-
Bake the Cookware: Preheat your oven to 375-400°F (190-200°C). Place the cookware upside down on the middle oven rack. To catch any oil drips, place a sheet of aluminum foil or a baking sheet on the lower rack.
-
Bake for an Hour: Let the cookware bake for about an hour. This process allows the oil to polymerize and form a hard, protective coating.
-
Cool in the Oven: Turn off the oven and let the cookware cool inside the oven. This slow cooling process helps the seasoning set properly.
-
Repeat as Needed: For best results, repeat the oiling and baking process 2-3 times.
How to Clean Rusted Cast Iron Cookware
Cleaning rusted cast iron cookware requires some effort, but it can be restored to its former glory with the right approach:
-
Scrub Off the Rust: Use a stiff brush, steel wool, or a scouring pad to scrub off as much rust as possible. If the rust is particularly stubborn, you can create a paste with baking soda and water and use it as an abrasive cleaner.
-
Rinse and Dry: After scrubbing, rinse the cookware thoroughly with water to remove all the rust particles. Dry it immediately and completely with a clean towel to prevent further rusting.
-
Re-season the Cookware: Once the rust is removed and the cookware is dry, it will need to be re-seasoned. Follow the curing steps mentioned above to reapply a protective layer of oil.
-
Maintain Regularly: To prevent rust from forming again, always ensure the cookware is completely dry before storing it. Apply a light coating of oil after each use and storage.
By following these steps, your cast iron cookware can remain in excellent condition and provide many years of reliable service.
