Why We Love Cooking with Cast Iron

Cooking with cast iron offers a range of benefits that make it a favorite among both home cooks and professional chefs. One of the biggest advantages is its ability to retain and distribute heat evenly, making it ideal for cooking at high temperatures and achieving perfect sears on meats and vegetables.

Cast iron cookware is incredibly durable and, with proper care, can last a lifetime or even be passed down through generations. It naturally develops a non-stick surface through the seasoning process, eliminating the need for synthetic coatings. Additionally, cast iron can be used on a variety of heat sources, from stovetops and ovens to campfires, making it versatile and adaptable.

Beyond its cooking performance, cast iron is a healthier choice since it doesn’t leach harmful chemicals, and it can even add trace amounts of dietary iron to food. These benefits, paired with its rustic charm and timeless appeal, make cast iron a valuable tool in any kitchen. So let’s learn how to make a proper seasoning paste to keep our cast iron in good shape!

Ingredients You’ll Need for Cast Iron Seasoning Paste

• 1.5 tablespoons of grass-fed tallow
• 1.5 tablespoons of beeswax pellets
• 1 tablespoon of avocado oil

Instructions for Creating Cast Iron Seasoning Paste

Prepare Your Workspace

Set up a double boiler on your stovetop. If you don’t have a double boiler, use a heat-safe bowl placed over a pot of simmering water. This ensures the ingredients melt gently without scorching. Gather all your ingredients, a small whisk or spoon, and your storage container (a 4-ounce tin or mason jar).

Melt the Tallow and Beeswax

Add the grass-fed tallow and beeswax pellets to the top section of your double boiler. Stir occasionally with a whisk or spoon to help the ingredients melt evenly. This process typically takes 5-10 minutes on low heat. Make sure the water in the pot below is simmering, not boiling, to prevent overheating.

Incorporate Avocado Oil

Once the tallow and beeswax have completely melted and combined, add the avocado oil. Stir the mixture thoroughly to ensure the oil is evenly blended. The addition of avocado oil provides extra pliability to the paste and boosts its seasoning power.

Pour into the Container

Carefully pour the melted mixture into a clean, dry 4-ounce tin or mason jar. Use a funnel if needed to avoid spills. Be cautious, as the mixture will be hot.

Let the Paste Harden

Allow the paste to cool and harden at room temperature for about 1-2 hours. Do not place the container in the refrigerator, as this may cause the paste to harden unevenly. Once fully set, the paste should have a smooth, firm texture.

Seal and Store

Once the paste has cooled and solidified, securely seal the container with a lid. Store the seasoning paste at room temperature in a cool, dry place. Proper storage will keep the paste fresh and ready to use for months.

Why Seasoning Paste is Important

Seasoning your cast iron pots and pans is crucial for creating a non-stick surface, protecting against rust, and maintaining the overall integrity of your cookware. The process involves applying a thin coat of oil, heating it to a high enough temperature to polymerize, and repeating the process to build up layers of seasoning. This paste simplifies the seasoning process by providing a ready-to-use blend of oils and fats with a higher smoke point.

How to Use the Seasoning Paste

Clean Your Cast Iron Thoroughly

Start by cleaning your cast iron skillet or cookware with warm water and, if necessary, a small amount of dish soap. Use a gentle scrub brush or sponge to remove food particles and any existing residue. Rinse well and immediately dry the skillet with a paper towel or clean kitchen cloth to prevent rust. If your skillet has stubborn residue, sprinkle some coarse salt on the cooking surface and scrub gently before rinsing.

Preheat Your Cast Iron (Optional)

To ensure the cast iron is completely dry and ready to absorb the seasoning paste, place it on the stovetop over low heat for 2-3 minutes. This step helps open the pores of the metal, allowing the oil to bond more effectively.

Apply the Seasoning Paste

Using a clean, dry paper towel, scoop a small amount of the seasoning paste and rub it onto the skillet’s surface. Be sure to apply a thin, even layer across the entire cooking surface, sides, and exterior. Avoid over-applying, as excess oil can create a sticky residue when heated.

Buff Off Excess Oil

Once you’ve applied the paste, use another clean paper towel to buff off any excess oil. This step is crucial to ensure a smooth, non-stick finish and prevent the paste from pooling or becoming gummy during the seasoning process.

Heat the Cast Iron

Preheat your oven to a high temperature, typically 450–500°F. Place the skillet in the oven upside down on the middle rack to allow any excess oil to drip off. Line the lower rack with aluminum foil or a baking sheet to catch drips and avoid a smoky mess in your oven.

Bake for One Hour

Let the skillet bake for an hour at high heat to polymerize the oil and create a durable, protective layer on the surface. After the hour, turn off the oven and allow the skillet to cool inside the oven completely. This gradual cooling helps the layers of seasoning bond more effectively.

Repeat the Process (If Needed)

For new pans, cast iron skillets from a thrift store, or cookware with damaged seasoning, repeat this process 2-3 times to build up a robust, non-stick surface. Over time, regular use and seasoning will enhance the skillet’s performance and appearance.

Maintain Your Cast Iron

After cooking, clean your cast iron with warm water and avoid using dish soap unless necessary. Apply a small amount of seasoning paste to the skillet while it’s still slightly warm to maintain the protective layer. Buff it with a paper towel for a smooth finish.

Best Oils for Seasoning Cast Iron

1. Avocado Oil: A good option because of its high smoke point and neutral taste.
2. Flaxseed Oil: Popular among great chefs for its ability to create a durable, non-stick surface.
3. Grapeseed Oil and Sunflower Oil: Both have a neutral taste and high enough temperature to work well in the seasoning process.
4. Animal Fats: Grass-fed tallow and bacon grease are traditional favorites due to their health benefits and ability to withstand high heat.

**Avoid oils with low smoke points, such as extra virgin olive oil, as they can leave a sticky residue.

Tips for Maintaining Cast Iron Cookware

Clean Promptly After Use

After cooking, clean your cast iron cookware while it is still warm. Use warm water and a gentle scrub brush or sponge to remove food residue. For stubborn stuck-on bits, scrub with coarse salt and a small amount of warm water to avoid damaging the seasoning layer.

Avoid Harsh Detergents and Soaking

Dish soap is generally unnecessary and can strip the seasoning if overused. Avoid soaking your cast iron in water for extended periods, as this can lead to rusting and weaken the protective layer.

Dry Thoroughly

Always dry your cast iron cookware immediately after washing. Use a lint-free kitchen towel or paper towel to remove all moisture. For extra assurance, place the cookware on the stovetop over low heat for a few minutes to evaporate any remaining water.

Re-Season Regularly

Re-season your cast iron as needed, especially if you notice food sticking or dull, patchy spots on the surface. Use your homemade seasoning paste to create a smooth, durable finish. Regular seasoning keeps your cookware in optimal condition.

Cook with the Right Oils

Use oils with a high smoke point when cooking, such as avocado oil, animal fats, or grapeseed oil. These oils help strengthen the layers of seasoning while cooking, unlike low smoke point oils that can break down the seasoning.

Store in a Dry Place

Always store your cast iron cookware in a dry, well-ventilated area at room temperature. Avoid stacking heavy items directly on cast iron, as this can cause scratches or damage to the surface. If stacking is necessary, place a layer of paper towel or a cloth between pieces to protect the seasoning.

Avoid Abrasive Tools

Do not use steel wool or abrasive cleaning pads on your cast iron, as they can strip the seasoning layer. Stick to soft sponges, gentle scrub brushes, or specialty cast iron scrapers designed for cleaning.

Preheat Gradually

When using your cast iron on the stovetop, avoid placing it on high heat right away. Gradually preheat over low to medium heat to prevent thermal shock, which can warp the cookware or damage the seasoning.

Handle Acidic Foods with Care

While cast iron is versatile, cooking highly acidic foods like tomatoes, citrus, or vinegar-based dishes for extended periods can break down the seasoning layer. If you plan to cook acidic foods, ensure the cookware has a well-established seasoning.

Keep an Eye on Rust

If you notice any rust, don’t panic. Rust can usually be removed with a gentle scrubbing of coarse salt and a small amount of oil. Re-season the cookware immediately after removing rust to restore the protective layer.

Never Cook with Cold Cookware

Avoid starting with a cold skillet, as it can cause uneven cooking and stickiness. Always preheat your cookware before adding ingredients.

Involve a Quick Maintenance Routine

After every use, quickly clean and dry the cookware, then add a light coat of oil. This habit takes only a few minutes and ensures your cast iron remains in great condition for a long time.

Conclusion

In conclusion, homemade cast iron seasoning paste is a simple yet powerful tool for maintaining your cast iron cookware. With its blend of natural ingredients and ease of use, this paste provides a reliable way to build and maintain the protective layers that give cast iron its legendary non-stick surface and durability.

Whether you’re working with new pans, thrift store finds, or your favorite skillet passed down through generations, this seasoning paste ensures your cookware stays in excellent condition for years to come. By taking the time to care for your cast iron, you’re not just preserving a cooking tool—you’re embracing a tradition of culinary excellence and creating a legacy of great meals to share with family and friends.
