How to season an iron cast pan

Seasoning an iron cast pan is a simple process, but it does require some time and patience. Here is a step-by-step guide on how to season your iron cast pan:

Step 1: Choose the Right Oil

The first step is to choose an oil that is suitable for seasoning. Some popular options include canola, vegetable, grapeseed, or flaxseed oil. It is important to avoid saturated fats like lard and coconut oil, as they do not create sufficient bonding points for carbon molecules to adhere to the pan.

Step 2: Preheat the Oven

Preheat your oven to a temperature between 200-350 degrees Fahrenheit. The ideal temperature is just below the smoke point of your chosen oil, as this will ensure that the oil fully polymerizes and bonds with the iron.

Step 3: Prepare the Pan

While the oven is heating up, prepare the pan by coating it with a thin layer of oil. Use a paper towel to rub the oil in concentric circles on the cooking surface, bottom, and handle of the pan. Make sure to wipe away any excess oil, leaving a super-thin layer that should look and feel dry to the touch.

Step 4: Place the Pan in the Oven

Once the oven has reached the desired temperature, place the pan inside. Leave the pan in the oven for about 30-60 minutes. This process may need to be repeated multiple times to create a strong base layer of seasoning.

Step 5: Increase the Temperature

After the initial seasoning, increase the oven temperature to 400 degrees Fahrenheit. Place the pan back in the oven for another hour. Do not open the oven door during this process to maintain a constant temperature.

Step 6: Let the Pan Cool

Once the hour is up, turn off the oven and let the pan cool down inside. This curing process helps to strengthen the seasoning.

Step 7: Use and Maintain Your Pan

After the initial seasoning process, your pan is ready to use! Each time you cook with oil or fat, you will be adding to the seasoning layer. It is important to avoid highly acidic foods, like tomatoes or citrus, in the early life of your seasoned pan as they can eat away at the seasoning. With regular use and proper care, your iron cast pan will develop a natural non-stick surface that will only get better with time.

The importance of seasoning

Seasoning a cast iron pan is important for several reasons. Firstly, iron is highly reactive and prone to rusting, even within minutes in humid air. Cooking in an unseasoned iron pan can cause rusting and sticking. Seasoning creates a protective coating that prevents rust and ensures food doesn't stick to the pan.

The seasoning process involves bonding thin layers of fat (such as oil) to the iron through heat. This process, known as polymerization, converts the fat into a form of plastic, resulting in a hard, blackened skin that protects the metal. While a new cast iron pan may come with some degree of pre-seasoning, it is recommended to add a few more layers to ensure optimal performance.

There are various methods and oils suggested for seasoning. Some sources recommend grapeseed oil, while others suggest flaxseed oil, Crisco, lard, or canola oil. The oven temperatures also vary, with some recommending a lower temperature of 200 degrees Fahrenheit for a slower bake, while others suggest blasting the oven at its highest temperature.

Regardless of the specific method chosen, the key to successful seasoning is to use the pan. Each time you cook with some type of fat, you add to the seasoning. This means that a well-seasoned cast iron pan is one that has been well-used. Even if your pan is lightly seasoned, you can still cook a variety of foods without worrying about sticking. However, it is recommended to avoid highly acidic foods like tomatoes, wine, citrus, and vinegar in the early stages of seasoning as they can eat away at the seasoning.

Oiling and heating process

To start cooking with a cast-iron pan, it is important to season it first. Seasoning a cast-iron pan involves creating a hard, protective coating by heating thin layers of fat (like oil) on the cast iron. This process gives the pan non-stick properties and prevents rusting. Here is a step-by-step guide to the oiling and heating process:

Step 1: Clean and Dry Your Pan

Start by giving your new cast-iron pan a quick rinse with warm water and mild soap. Use a lint-free cloth or paper towel to dry it promptly and thoroughly. It is important to ensure that your pan is completely dry before moving on to the next step.

Step 2: Preheat Your Pan

Place your clean and dry pan on the stove over low to medium heat for about 5 minutes. This step helps evaporate any lingering moisture and opens the iron's pores to better absorb the seasoning. Make sure to wear oven mitts or use a pot holder when handling the pan as it will become hot.

Step 3: Apply a Thin Coat of Oil

Once your pan is preheated, remove it from the heat and let it cool down slightly. Then, add a small amount of oil to the cooking surface, using a neutral oil like canola or vegetable oil. You only need about ⅛ teaspoon of oil, but start with a slightly larger amount to ensure even coverage. Use a paper towel or a clean cloth to rub the oil onto the entire cooking surface, including the bottom and handle of the pan. Make sure to wipe away any excess oil, leaving a thin, even coat.

Step 4: Heat the Oiled Pan

Place the oiled pan back on the stove over low to medium heat. Heat it for a few minutes until the oil begins to smoke slightly. This indicates that the oil is polymerizing and bonding to the iron, creating a protective layer. Be cautious and ensure proper ventilation during this step as the smoke may be irritating.

Step 5: Cool and Repeat

Turn off the heat and allow the pan to cool down completely. Once cooled, repeat steps 3 to 5 for a total of three to four times. With each repetition, you are building up layers of seasoning, creating a stronger and more durable non-stick surface.

After completing the final round of the oiling and heating process, let the pan cool down, and it will be ready for cooking! Remember that each time you cook with some type of fat, you will be adding to the seasoning of your pan.

Foods to avoid

While cast iron pans are versatile and can be used to cook most things, there are some foods that you should avoid cooking in them. Here are some foods to avoid when using a cast-iron pan:

Acidic Foods

Acidic foods like tomatoes, tomato-based sauces, vinegar, wine, lemon juice, and other citrus-based sauces should be avoided in cast-iron pans, especially for prolonged periods. The acid can react with the iron, causing a metallic taste in your food and breaking down the seasoning of the pan. This can lead to a porous surface that will impact the flavour of your food. However, a well-seasoned cast-iron pan can handle reasonable amounts of acidic foods without any noticeable change. It is recommended to cook bacon in the pan afterward to protect the seasoning.

Sticky Foods

Sticky foods like eggs, pancakes, and rice should be avoided in a new cast-iron pan that is not yet fully seasoned. These foods are more likely to stick to the pan, making it difficult to achieve the desired results and requiring more effort to clean. Instead, it is suggested to first sear meat and bacon for a few months to build up a non-stick layer before attempting to cook sticky foods.

Fish

Certain types of fish, such as flaky fillets like flounder and tilapia, are best avoided in cast-iron pans. The delicate nature of these fish makes them prone to sticking to the pan, even with the use of butter or oil. A non-stick pan is recommended for cooking such fish fillets to prevent them from falling apart.

Storing Leftovers

Cast-iron pans should not be used to store leftover food for prolonged periods. Leaving food in the pan can cause rusting and loss of seasoning. Additionally, the iron can leech into the food, creating an unpleasant taste. It is best to remove and store leftovers separately to maintain the condition of the pan and the quality of your food.

Cleaning and maintenance

Cast iron pans are durable and long-lasting, but they do require some care and maintenance to keep them in good condition. Here are some detailed instructions on how to clean and maintain your iron cast pan:

Washing and Cleaning

• Always wash your cast iron pan by hand. Do not put it in the dishwasher, as this can remove the seasoning and cause rust.
• Use a small amount of mild dish soap with hot water and a non-abrasive sponge or scrub brush to gently clean the pan. Avoid using steel wool or metal scrubbers, as they can damage the seasoning.
• For stuck-on food residue, use a pan scraper or a wooden spatula to remove it. You can also simmer a little water for 3-5 minutes to loosen the residue, then use the scraper after the pan has cooled.
• Dry the pan promptly and thoroughly with a lint-free cloth or paper towel. It is normal to see some black or dark residue on the towel, which is just the seasoning.
• If your pan has developed rust, you can remove it by scouring it with warm, soapy water and steel wool. Rinse and dry the pan thoroughly before re-seasoning it.

Seasoning

• Seasoning your cast iron pan creates a natural, non-stick finish and helps prevent rusting. A well-seasoned pan is key to great cooking performance.
• To season your pan, start by coating it with a thin layer of cooking oil or seasoning spray. Use a paper towel to wipe the surface until no oil residue remains.
• Place the pan upside down on the top rack of the oven and put a baking sheet or aluminium foil on the bottom rack to catch any drips.
• Set the oven temperature to 400-500 degrees Fahrenheit and bake the pan for one hour. Allow it to cool, and repeat the process as needed to achieve a classic black patina.
• You can also season your pan by cooking with it. Each time you cook with fat, you add to the seasoning. Start with low or medium heat and build up your initial layers of seasoning by cooking dishes like caramelised onions, fried chicken, or baked cornbread.
• Avoid using acidic foods like tomatoes, wine, citrus, or vinegar until you have a good layer of seasoning, as these can eat away at it.
• Some oils, like flaxseed oil, may create a brittle and flaky seasoning. Grapeseed oil is a good alternative that can be found in most supermarkets.
