The Mystery Of Cast Iron Pans: Nsf Or Not?

Cast iron pans are popular, especially for searing, and are generally safe to use. But they can leach iron, which is a strong pro-oxidant. Those genetically at risk for iron overload should learn more about cast iron safety.

Is cast iron safe?

Cast iron is a popular and traditional cookware material that has been used for centuries. It is durable, efficient, and versatile. However, there are some safety concerns associated with cast iron cookware that you should be aware of.

One of the main concerns with cast iron is its ability to leach iron into food. Cast iron is made primarily of iron, and when used for cooking, it can transfer some of this iron into your food. While iron is an essential mineral and can be beneficial for those who are anemic, too much iron can be harmful. Excess iron has been linked to various health conditions, including Alzheimer's, heart disease, and colorectal cancer. Those who are genetically at risk for iron overload, such as people with hereditary hemochromatosis, should be particularly cautious when using cast iron cookware.

Another concern with cast iron is the potential for it to rust if not properly seasoned. Seasoning involves coating the cast iron with oil and heating it, which creates a non-stick surface and protects against rust. A well-seasoned cast iron pan will also leach less iron into your food.

In addition to these concerns, cast iron pans are very heavy and can be difficult to maneuver, especially for those with wrist or hand issues. They also require special care and maintenance to prevent rusting and ensure optimal performance.

Overall, cast iron cookware is generally safe to use, but it is important to be aware of the potential risks and take appropriate precautions. Proper seasoning and maintenance of your cast iron cookware can help reduce the risk of iron leaching and rusting. For those with specific health concerns or allergies, other types of cookware, such as stainless steel or enameled cast iron, may be safer options.

Is cast iron non-stick?

Cast iron pans are a versatile workhorse in the kitchen. They can be used for searing, sautéing, braising, and baking. They are also durable, inexpensive, and retain heat well. When properly seasoned and cared for, cast iron pans develop a coating that prevents most foods from sticking. However, cast iron pans are poor conductors of heat and require seasoning.

Cast iron pans can deliver non-stick, without the chemicals, when properly seasoned and cared for. A well-seasoned cast iron pan will be non-stick enough for you to substitute it on most occasions. However, it is not anywhere near as non-stick as Teflon. You cannot dump a load of cold eggs into your cast iron pan, slowly heat it up with no oil, and then slide the cooked eggs right back out without a spot left behind.

To season a cast iron pan, heat it up on the stovetop until it's smoking hot, then rub a little oil into it and let it cool. Repeat this process a few times. Clean the pan after each use by washing it with soap and water and scrubbing out any gunk or debris from the bottom. Rinse out any excess soap with water, then place the skillet over a burner set to high heat. When most of the water inside the skillet has dried out, add a half teaspoon of neutral oil like vegetable, canola, flaxseed, or shortening. Rub it around with a paper towel. Continue heating the pan until it just starts to smoke, then give it one more good rub. Let it cool and you're done.

How do you season a cast iron pan?

Seasoning a cast-iron pan is a simple process that will ensure your cookware lasts for years. Seasoning refers to the hard, protective coating that is formed by heating thin layers of fat (like oil) on the cast iron. This coating will give your pan an almost nonstick quality and prevent it from rusting.

Step 1: Wash and Dry Your Pan

Start by giving your pan a good scrub with warm, soapy water. This is especially important if your pan is new, as you don't know what it has been exposed to during the manufacturing process and transportation. Dry the pan thoroughly with a towel or kitchen paper. You can also place the pan on a stovetop flame for a minute or two to drive off any lingering water.

Step 2: Rub with Oil

Once your pan is clean and dry, rub it all over, inside and out—including the handle—with cooking oil. It is best to use unsaturated cooking fats, like vegetable, canola, or corn oil, as these are easier to spread than saturated fats and are likely already in your kitchen. Flaxseed oil is also a popular choice but can be prone to flaking. The key is to apply the oil thinly and evenly, and then buff the pan so that it no longer looks greasy. You want the pan to feel almost dry to the touch. Using too much oil will cause your pan to become sticky.

Step 3: Heat in the Oven

Place the oiled pan in the oven. It is recommended to preheat the oven to between 350°F and 500°F (230°C and 260°C) . Place a baking sheet or aluminium foil on the bottom rack to catch any oil drips. Bake the pan for around 30 minutes to an hour. The oil will polymerize and form a hard, plastic-like coating. It may get a little smoky, so ensure your kitchen is well-ventilated.

Step 4: Repeat

Repeat steps 2 and 3 three to four times to set down a good initial layer of seasoning. Allow the pan to cool down completely before use.

Maintenance

To maintain your cast-iron pan, simply use it! Each time you cook with oil or fat, you will be adding more seasoning to the pan. You can also season your pan in the oven a few times a year to strengthen the bond. If you notice that the seasoning has been removed (by cooking acidic foods or using excessive heat, for example), simply repeat the seasoning process.

What foods should you cook in a cast iron pan?

Cast iron skillets are incredibly versatile and can be used for a variety of cooking tasks. Here are some foods you should cook in a cast iron pan:

• Steak
• Pies
• Dutch babies
• Cornbread
• Tortillas
• Pizza
• Eggs
• Chicken
• Hashbrowns
• Hamburgers
• Pancakes
• Tofu
• Chicken pot pie
• Whole roasted chicken
• Roasted brussel sprouts
• Stir-fry
• Fish

What foods should you avoid cooking in a cast iron pan?

Cast iron pans are great for cooking a variety of foods, but there are some things you should avoid cooking in them. Here is a list of foods you should avoid cooking in a cast iron pan:

• Acidic foods: Acidic foods like tomatoes can damage the seasoning of your skillet, and the end result will taste metallic, especially if it's something that requires a long cooking time.
• Wine-braised meats: It's not a great idea to cook foods that require deglazing with wine or vinegar in a cast iron skillet. The acid in these foods can leach small amounts of metal into your food, giving it an off-taste and potentially harming your health.
• Desserts: If you mainly cook savory foods in your skillet, those residual flavors can transfer into whatever you're baking, giving your dessert an unexpected flavor.
• Eggs: Omelets and other egg dishes can stick to the surface when you try to remove them from a cast iron skillet.
• Sticky foods: Like eggs, pancakes or fried rice can stick to a cast iron pan, especially when the pan is new and not well-seasoned yet.
• Delicate fish: Cast iron skillets are great for searing a steak, but the same heat retention that gives your steak a beautiful brown crust will probably be the end of your lovely piece of trout or tilapia. Save the delicate fish for the non-stick pan, but salmon and tuna steaks will cook perfectly in your cast iron pan, though, so feel free to try those out.
