Never do this to Cast-Iron

While this cookware is known for its durability and versatility, there are certain things you should avoid doing to maintain its quality and extend its lifespan. Remember, proper care and maintenance will help keep your cast iron cookware in excellent condition and ensure its longevity. Here are some things you should never do to cast iron:

Never soak in water for long periods: 

Avoid leaving skillets submerged in water for extended periods. Prolonged exposure to water can lead to rust formation and damage the seasoning. However, if you have stubborn food particles, soaking for 10-15 minutes should do the trick to loosen the food particles.

Never use harsh detergents or abrasive cleaners: 

Avoid using strong detergents, abrasive sponges, or steel wool. These can strip away the seasoning and scratch the surface of the cookware. 

Never put cold water on a hot cast iron pan: 

Rapid temperature changes can cause the skillet to crack. Avoid pouring cold water on a hot cast iron pan, as this thermal shock can lead to irreversible damage.

Never use acidic ingredients for prolonged periods: 

Avoid cooking highly acidic foods, such as tomatoes or citrus-based dishes, in a cast-iron pan for prolonged periods. Acidic ingredients can break down the seasoning and potentially leach iron into the food.

Never store food in cast iron for extended periods: 

For extended periods, leaving food in cast iron can lead to flavor absorption and potential rusting. Transfer leftovers to other storage containers after cooking.

Never use high heat unnecessarily: 

While cast iron is excellent at retaining and distributing heat, excessively high heat can cause damage. Avoid using the highest heat settings unless necessary, as it can lead to warping or cracking.

Never neglect to dry thoroughly: 

After cleaning your skillet, dry it thoroughly to prevent rust formation. Leaving it wet can promote rust and degrade the seasoning. Place your skillet on medium heat until it is completely dry.

Why You Should Consider Using a Separate Skillet for Fish and Acidic Foods

Using a separate skillet can make a difference when cooking delicate fish or preparing dishes with acidic sauces that feature ingredients like lemon juice or vinegar. While it may seem like an extra step in your culinary routine, there are good reasons to consider this approach. In this article, we’ll explore the benefits of using separate skillets for fish and acidic foods, highlighting why it’s a good idea for achieving optimal flavors and preserving the quality of your cookware.

Additionally, Simmering sauces for an extended period of time in your skillet, especially sauces like long-simmered tomato sauce, is generally not a good idea. The acidic nature of tomatoes can react with the surface of your pan, potentially eroding the layer of seasoning that helps protect and enhance the performance of your seasoned cookware. This can lead to a loss of the non-stick properties and may affect the overall quality of your skillet. It’s advisable to use a non-reactive pot or saucepan for simmering sauces for prolonged periods to ensure the longevity of your skillet’s seasoning.

For several reasons, using separate skillets is a good idea When cooking fish or preparing dishes with acidic sauces. It allows you to protect the fish, preserve the integrity of acidic sauces, prevent odors and flavors from lingering, and simplify the cleaning and maintenance process. By dedicating specific skillets for these purposes, you can ensure that each dish shines with its distinct flavors while extending the lifespan and quality of your cookware. So, consider incorporating separate skillets into your kitchen routine and elevate your culinary creations to new heights.

Commonly Asked Questions

These guidelines are meant to help you maintain the quality and longevity of your cast iron cookware. With proper care, your new cast iron skillet can last for generations. Here are some commonly asked questions about things you should never do to cast iron:

Can I put my cast iron pan in the dishwasher? 

No, you should never put cast iron pans in the dishwasher. The dishwasher’s harsh detergents and high heat can strip away the seasoning and potentially cause rusting. It’s best to hand wash your cookware.

Is it safe to use metal utensils on cast iron? 

While avoiding metal utensils with sharp edges on cast iron is generally recommended, it’s not inherently unsafe. Metal utensils can potentially scratch or damage the seasoned surface, so it’s better to opt for wooden spoons, silicone, or nylon utensils to preserve the seasoning. If you choose to use metal utensils, just be mindful not to gauge into your skillets.

Can I use soap to clean my skillet? 

Using soap to clean your cast iron pan is generally acceptable, as long as you use mild dish soap and don’t scrub too vigorously. However, using soap every time you clean your cast iron is unnecessary. Wiping it clean with hot water and a gentle scrub is often sufficient.

Can I cook acidic foods in my cast iron pan? 

While it’s generally advised to avoid cooking highly acidic foods for prolonged periods in cast iron, cooking acidic dishes for a short duration is usually fine. Just clean and re-season the skillet afterward to maintain its quality.

Is it okay to leave food in cast iron overnight?

 Leaving food in your skillets overnight is not recommended. It can lead to flavor absorption, potential rusting, and degradation of the seasoning. It’s best to transfer any leftovers to other storage containers after cooking.

What are the myths about using cast iron skillets?

It’s important to separate fact from fiction when using cast iron skillets. You can make the most of your cookware by understanding the proper care and debunking the myths. There are several myths surrounding the use of cast iron skillets. Let’s debunk some of the common ones:

Myth 1: It is always non-stick. 

Reality: While a well-seasoned cast iron skillet can develop a natural non-stick surface, it requires proper maintenance and use. However, this non-stick property is not as slick as modern non-stick pans. Some foods, like eggs, can still stick if not cooked properly.

Myth 2: You should never use soap to clean cast iron. 

Reality: Using mild dish soap to clean your cookware is perfectly safe. Contrary to the myth, using soap won’t strip away the seasoning if done sparingly. Just be sure to dry the skillet thoroughly to prevent rusting.

Myth 3: Acidic foods will always strip the seasoning. 

Reality: While cooking highly acidic foods for prolonged periods can erode the seasoning, cooking them for a short duration is usually safe. The seasoning layer on a well-maintained skillet is relatively resilient. However, cleaning and re-seasoning the pan after cooking acidic dishes is a good practice to ensure its longevity.

Myth 4: Never cook with cast iron on a glass stovetop. 

Reality: It is generally safe to use cast iron on a glass stovetop. However, you must handle it carefully to prevent scratching the surface. Avoid sliding the skillet and lift it when moving. Also, be mindful of the weight; cast iron pans can be heavy and damage the glass if dropped.

Myth 5: You need to season cast iron continuously. 

Reality: While it’s essential to season cast iron initially and periodically maintain it, you don’t need to season it every time you use it. Seasoning builds up over time with proper use and care. Regular cooking and cleaning with oil help maintain and enhance the seasoning layer.

Myth 6: It is difficult to maintain

Reality: While there is a common perception that cast iron is difficult to maintain & it’s actually quite simple. These skillets are built to last for years with proper care.

Maintaining Cast Iron is a Simple Process

I have shared the process for caring for your cast iron. Following these simple steps makes cast iron maintenance a routine and easy task. With proper care, your cast iron cookware can last for generations and provide excellent cooking performance.

Seasoning: 

Seasoning is building a protective layer on the surface of cast iron. It involves applying a thin coat of oil and heating it to create a polymerized layer. Once properly seasoned, the skillet becomes more non-stick and resistant to rust. Seasoning can be done initially when you first acquire the skillet and periodically as needed. It’s a straightforward process that helps maintain and improve the quality of your cookware.

Cleaning: 

Contrary to the myth, cleaning cast iron doesn’t have to be a daunting task. After cooking, allow the skillet to cool down slightly, then use hot water and a gentle brush or sponge to clean it. Mild dish soap can be used sparingly if desired. Avoid using harsh detergents, abrasive cleaners, or steel wool, as they can strip away the seasoning. After cleaning, thoroughly dry the skillet to prevent rusting.

Oil maintenance:

Applying a thin layer of oil after each use is beneficial to keep your cast iron in good condition. This helps maintain the seasoning of the pan and protects the surface from moisture. You can use a small amount of oil, such as vegetable oil or flaxseed oil, and rub it onto the skillet using a paper towel or cloth. Wiping off any excess oil, as too much oil will cause it to become sticky or stinky.

Proper storage: 

Store your cast iron skillet in a dry place to prevent moisture buildup and rusting. If stacking multiple pieces, you can place a paper towel or cloth between them to prevent scratching. Proper storage ensures that your cast iron remains in good condition between uses.

Final Thoughts…

 Knowing the things you should never do to cast iron is essential for maintaining the quality and longevity of your beloved cookware. By avoiding these common mistakes, you can protect your investment and continue to enjoy the benefits of cooking with cast iron. By following these guidelines, you can maintain the integrity of your cookware and enjoy its excellent cooking performance. With proper care, your skillet or Dutch oven can become a cherished kitchen companion, passing it down through generations.
