The Cast Iron Conundrum: To Cure Or Not To Cure?

Curing a cast iron pan is a process that involves coating the pan with grease or oil and then oven-cooking it to set the finish. This fills the cast iron pores and creates a natural, non-stick coating. The process is also known as seasoning, and it is necessary to cure a cast iron pan before using it for the first time.

The importance of curing cast iron pans

Curing a cast iron pan, also known as seasoning, is an important process that ensures your cookware is ready for use and has a long lifespan. Cast iron is highly reactive and prone to rusting, so curing your pan will protect it and enhance its performance. Here are some key reasons why curing your cast iron pan is essential:

Protection from Rust:

Iron, when exposed to humid air, can quickly develop rust. Curing your cast iron pan creates a protective coating that shields the iron from moisture and prevents rusting. This protective layer is formed by bonding fat or oil to the metal through a process called polymerization.

Non-Stick Properties:

The curing process results in a natural, non-stick coating on your pan. By filling the cast iron's pores with oil and oven-cooking it, you create a smooth surface that food is less likely to stick to. This makes cooking and cleaning easier and more enjoyable.

Even Heat Distribution:

Cast iron is known for its excellent heat distribution properties. Curing your pan helps maintain this advantage by ensuring an even coating of oil, which promotes uniform heat distribution. This results in better cooking performance and more consistent results.

Longevity:

A well-cured cast iron pan can last a lifetime, or even generations, with proper care. The protective coating formed during curing protects the iron from corrosion and other types of damage. This extends the lifespan of your cookware, making it a worthwhile investment.

Enhanced Cooking Experience:

A cured cast iron pan provides an optimal cooking surface for various dishes. It is perfect for frying, searing, roasting, and baking. The non-stick properties and even heat distribution ensure that your food cooks evenly and releases easily from the pan.

Easy Maintenance:

While curing a cast iron pan may seem like a tedious task, it actually reduces the maintenance required in the long run. Once cured, cast iron cookware care is simple and straightforward. Regular use of your pan will continue to build up the seasoning, improving its performance and durability.

In summary, curing your cast iron pan is a crucial step in preparing your cookware for use. It protects the iron, enhances its performance, and extends its lifespan. By taking the time to properly cure your cast iron pan, you'll be rewarded with a durable, versatile, and reliable piece of cookware that will serve you well for years to come.

How to cure a cast iron pan

Curing a cast iron pan is a simple process that will ensure your cookware lasts a lifetime.

Step 1: Wash and Dry

First, scrub your pan with hot, soapy water to ensure there is no food residue, grime, or rust. Dry it completely.

Step 2: Oil

Warm the pan slightly and apply a thin coat of oil or melted grease to the inside, outside, lid, and handle. You can use vegetable, canola, corn, or peanut oil. Do not use liquid cooking oils.

Step 3: Bake

Preheat your oven to between 350-500°F. Place the cookware upside down on a foil-covered baking sheet to catch any drips. Bake for 20 minutes to several hours, depending on the condition of the pan. If it starts to smoke, reduce the temperature by 10-15°F until the smoking stops.

Step 4: Cool

Turn off the oven and let the pan cool down naturally before removing it.

Step 5: Repeat

Repeat the process several times to build up a strong layer of seasoning.

Maintenance:

• To maintain the curing, rinse or wash your pan with mild soapy water after each use. Some cooks simply wipe the pan with a wet cloth.
• Avoid scrubbing or immersing the pan in hot water for several minutes, as this can remove the curing.
• Use your pan regularly to build up the seasoning over time.

How to maintain a cured cast iron pan

Maintaining a cured cast iron pan is simple, but it does require some care to keep it in top shape. Here are some tips to help you maintain your cured cast iron pan:

Washing and Drying:

• Wash your cast iron pan by hand with mild soap and hot water. Use a small amount of soap to avoid stripping the seasoning.
• For stuck-on food, simmer a little water for a few minutes to loosen it, then use a nylon scrubbing brush or a pan scraper to remove it.
• Dry the pan promptly and thoroughly with a lint-free cloth or paper towel. Make sure there is no remaining moisture, as it can cause rusting.

Oil Application:

• After drying, apply a very light layer of cooking oil or seasoning spray to the surface of the pan. Use a paper towel to wipe the surface until no oil residue remains.
• You can use a variety of oils, such as vegetable, canola, corn oil, or specially formulated seasoning oils. Avoid using liquid cooking oils.

Oven Seasoning:

• It is recommended to season your cast iron pan in the oven a few times a year to strengthen the seasoning.
• Preheat your oven to 450-500 degrees Fahrenheit.
• Apply a thin, even layer of cooking oil to the inside and outside of the pan.
• Place the pan upside down on the top rack of the oven, with a baking sheet or aluminium foil on the rack below to catch any drips.
• Bake for one hour.
• Allow the pan to cool completely before removing it from the oven.

Daily Use:

• Use your cast iron pan regularly. Each time you cook with oil, you add another layer to the seasoning.
• Avoid cooking acidic foods or using excessive heat, as these can break down the seasoning.
• Avoid using abrasive utensils or scouring pads, as they can remove the seasoning.
• If you notice any rust spots, scour the area with warm, soapy water and steel wool. Rinse and dry thoroughly, then rub with vegetable oil.

By following these steps, you can maintain the curing on your cast iron pan and enjoy its non-stick and even heat distribution properties for years to come.

How to restore a rusty cast iron pan

Cast iron skillets are naturally prone to rust, but they can be restored with a few simple steps. Here is a guide on how to restore a rusty cast-iron pan.

Step 1: Remove Rust

Use fine steel wool or a scouring pad to scour the rusty sections of the pan until the area returns to raw cast iron. If the rusting is minor, a salt scrub may be enough. For more serious cases, you can soak the pan in a mixture of equal parts water and distilled white vinegar. Check the pan every 15 minutes and remove it from the solution once the rust easily flakes away.

Step 2: Wash the Pan

Wash the pan with warm water and mild dish soap. Scrub with a bristle brush, gentle scouring pad, or mesh sponge if needed.

Step 3: Dry the Pan

Thoroughly dry the pan immediately with a clean cloth or paper towels. You can place it on the stovetop on low heat for a few minutes to ensure it is completely dry.

Step 4: Oil the Pan

Apply a thin coating of vegetable oil or cooking oil of your choice to the entire pan, including the bottom and handle. Use only a small amount to avoid a sticky surface.

Step 5: Place the Pan in the Oven

Place the cast iron upside down on the top rack of your oven. Place a sheet of aluminum foil or a foil-lined baking sheet on the bottom rack to catch any oil drips. Heat the cast iron for about an hour at 350-500°F.

Step 6: Let the Pan Cool

Turn off the heat and let the cast iron cool down before using it again.

Tips for Maintaining Your Cast Iron Pan

• Never soak the pan in water as cast iron is vulnerable to rust.
• Don't let the pan air-dry. Wipe off any excess water with a towel and place it on the burner to remove extra moisture.
• Lightly oil the pan after use. Once dried, rub your skillet with a thin layer of vegetable oil before storing.

With these steps and tips, you can restore and maintain your cast-iron pan, keeping it in top shape for years to come.

What to cook in a cast iron pan

A cast iron pan is a versatile piece of cookware that can be used for various dishes, from savoury to sweet. Here are some tips and recommendations for what to cook in your cast iron pan:

Pre-heat Your Pan

It is important to pre-heat your cast iron pan gradually on a similar-sized burner to ensure even heating. Cast iron retains heat well, so you don't need to use a high heat setting. Preheating also helps prevent food from sticking to the pan. Don't forget to use a handle mitt, as cast iron handles can get extremely hot.

Oiling Your Pan

When using a cast iron pan, it is recommended to add a small amount of oil or fat before adding your food. If you want to use butter, start by adding oil to the pan first, and then add butter just before adding your food.

What to Cook

Cast iron pans are great for searing meat, such as steak, as they create a crispy, caramelized crust. You can also use your cast iron pan for cooking vegetables, such as crispy cauliflower, pan-roasted cabbage slaw, or charred peppers for tacos. If you're feeling adventurous, try making a vegetarian chilli with mustard-roasted red potatoes.

Cast iron pans are also perfect for cooking eggs, as the even heat distribution ensures even cooking and prevents sticking. You can also use your cast iron pan for baking, such as making a cheese, veggie and ham frittata or a smoked cheddar and jalapeno cornbread.

What Not to Cook

While cast iron pans are versatile, it is recommended to avoid cooking acidic foods such as tomatoes, wines, and vinegars frequently, as these can break down the seasoning on the pan. If you do cook acidic foods, you may need to reseason your pan before cooking other dishes.

Additionally, avoid cooking flaky fish or meats with delicate skin in your cast iron pan, as they may have trouble releasing from the pan and fall apart when flipped.

Multiple Cast Iron Pans

Consider having multiple cast iron pans for different types of dishes. For example, you may want to have one pan specifically for desserts and sweet recipes and another for meats, sauces, and vegetables. This helps prevent flavour transfer between dishes.
