The History of Cast Iron Cookware

Cast iron cookware has a rich and fascinating history that spans centuries and continents. The Chinese can be credited with pioneering the use of cast iron cookware during the Han Dynasty, which lasted from 206 BCE to 220 CE. The use of cast iron spread across Asia, and by the time it made its way to Europe, it was already a well-established method of cooking.

During the Middle Ages, cast iron cookware became increasingly popular in Europe, and the art of casting iron became a highly skilled craft. In the United States, it was not until the 18th century that cast iron cookware became popular. In fact, the first cast iron foundry in America, Saugus Iron Works, was not established until 1645, in Lynn, Massachusetts. From its humble beginnings, cast iron cookware has become an iconic symbol of traditional cooking, with a legacy that has endured for centuries.

Why Use Cast Iron Cookware?

Cast iron cookware has many benefits, which is why it is so popular. Cast iron cookware is durable and can last for generations. It is also an excellent conductor of heat, which makes it ideal for cooking. Cast iron cookware is also versatile and can be used on a variety of cooking surfaces, including stovetops, ovens, and grills.

Types of Cast Iron Cookware

There are many types of cast iron cookware, including skillets, Dutch ovens, grill pans, and woks. Skillets are the most popular type of cast iron cookware and can be used for a variety of cooking tasks, including frying, sautéing, and baking. Dutch ovens are ideal for slow-cooking stews, soups, and casseroles. Grill pans are perfect for grilling meats and vegetables, and woks are great for stir-frying.

Seasoning Your Cast Iron Cookware

What is Seasoning?

One of the most crucial steps in maintaining cast iron cookware is seasoning. Seasoning helps to create a non-stick surface on the cookware and prevents it from rusting.

How to Season Your Cast Iron Cookware

To season your cast iron cookware, you need to apply a thin layer of oil to the surface and then heat it in the oven. This process will polymerize the oil, creating a non-stick surface that is easy to clean and maintain. You should season your cast iron cookware regularly to keep it in excellent condition.

1. Preheat your oven to 400 degrees Fahrenheit and adjust the oven racks to the two lowest positions.
2. To prepare the cast iron piece for seasoning, first wash it in hot, soapy water using a stiff brush to remove any stuck-on food. If you notice any surface rust, use fine steel wool to remove it. Rinse the piece thoroughly and towel-dry it immediately. If you are only adding to the seasoning, simply rinse it in water and dry it thoroughly.
3. Using a paper towel, lightly coat every surface of the cast iron piece, including the underside of lids and handles, with oil or shortening.
4. Place a large sheet of aluminum foil on the lowest oven rack and set the cast iron piece upside down on the rack above it. If there is a lid, set it beside the piece. Bake for 1 hour.
5. After the baking is complete, turn off the oven and keep the oven door closed. Allow the cast iron piece to cool completely to let the seasoning slowly cool and form a hard finish. The seasoning will initially have a dark champagne color, but it will darken over time with use and more seasoning.
6. It’s recommended to season a cast iron piece that has never been seasoned before at least twice before using it.

What Oil Should You use to Season Cast Iron Cookware?

I’ve used everything from vegetable oils, coconut oil, shortening, and even lard. They all formed a great finish. A trend has developed that uses flax seed oil for the most durable finish. America’s Test Kitchen tried it out – see their findings at The Ultimate Way to Season Cast Iron

How to Clean Cast Iron Cookware

Cleaning your cast iron cookware is essential to keep it in good condition. If you don’t clean it correctly, food residue can build up, making it challenging to cook with and creating a breeding ground for bacteria.

To clean your cast iron cookware, rinse it with hot water. Use a stiff brush to remove any stuck on food. If needed, use a small amount of kosher salt to help remove stubborn stuck-on food. Avoid using soap or a dishwasher, as they can remove the seasoning from the cookware. 

There are specially designed stainless steel scrubbers that look a bit like chain mail that are really great for scrubbing stuck and burnt food from your cookware.

Dry your cookware thoroughly after washing to prevent rust. I like to put my cast iron on a low flame to dry them completely. 

While the cast iron is still warm lighty apply a very thin layer of shortening using a paper towel. Using shortening will prevent any off flavors from developing that can happen with vegetable oils and long storage periods.

How to Store Cast Iron Cookware

Proper storage is essential to maintain the quality of your cast iron cookware. If you store it improperly, it can rust, and the seasoning can deteriorate.

To store your cast iron cookware, you should make sure it’s completely dry before putting it away. You can store it in a dry place, such as a cupboard or pantry, or hang it on a wall.

 It’s best to store your cookware with a paper towel or cloth to prevent moisture from accumulating. Place a paper towel between the lid and bottom of your cast iron to allow air to circulate.

Tips for Cooking with Cast Iron Cookware

When cooking with cast iron cookware, there are a few tips to keep in mind to ensure your food turns out perfectly every time. First, preheat the cookware before adding any food. This helps to create a non-stick surface and ensures even cooking. Second, use a high smoke point oil, such as vegetable oil or canola oil, when cooking with cast iron. Third, avoid using metal utensils on the cookware, as they can scratch the seasoning. Fourth, never put cold liquid into hot cast iron cookware, as it can cause the cookware to crack.

How to Revive Old Cast Iron Cookware

If your cast iron cookware is looking a little worse for wear, don’t worry! It is possible to revive old cast iron cookware. First, use a stiff brush to remove any rust or food particles. Next, apply a layer of vegetable oil to the cookware and place it in a 350°F oven for 1 hour. Let the cookware cool before removing it from the oven. Repeat this process until the cookware is fully re-seasoned.

Common Mistakes to Avoid When Using Cast Iron Cookware

While cast iron cookware is versatile and easy to use, there are a few common mistakes that can damage the cookware or affect the taste of your food. First, avoid using soap or harsh detergents when cleaning cast iron cookware, as they can damage the seasoning. Second, never soak cast iron cookware in water, as it can cause rusting. Third, avoid using acidic foods, such as tomatoes or vinegar, in cast iron cookware, as they can damage the seasoning. Fourth, do not overheat cast iron cookware, as it can cause warping or cracking.

Cast Iron Cookware Versus Other Materials

Cast iron cookware is not the only type of cookware available. There are many other materials, including stainless steel, aluminum, and non-stick. While each material has its benefits, cast iron cookware is unique in its ability to distribute heat evenly and create a non-stick surface without the use of chemicals.

Cast Iron Cookware and Health
