America's Test Kitchen - How to Clean and Season a Cast-Iron Pan | America's Test Kitchen (S24 E21)
The video explains that caring for a cast iron pan is straightforward and not as complicated as often perceived. For enameled cast iron, regular washing and scrubbing suffice. For plain, uncoated cast iron, after each use, rinse and scrub under hot water using a scrub brush, avoiding soap to prevent rust. Dry the pan on medium heat, then apply a small amount of vegetable oil, wiping it with paper towels until it appears dry. This process helps maintain the pan's seasoning. If food is stuck or rust appears, heat vegetable oil in the pan, add kosher salt, and scrub with paper towels to clean. This method acts as both an exfoliant and moisturizer for the pan. Regular maintenance will improve the pan's performance over time.
Key Points:
- Rinse and scrub cast iron under hot water after each use; avoid soap to prevent rust.
- Dry the pan on medium heat and apply a small amount of vegetable oil to maintain seasoning.
- Use kosher salt and oil to scrub off stuck food or rust, acting as an exfoliant.
- Regular maintenance enhances the pan's performance and longevity.
- Enameled cast iron requires only regular washing and scrubbing.
Details:
1. 🛠️ The Resilience of Cast Iron
- Maintaining a cast iron pan is simpler than perceived; regular seasoning and avoiding prolonged exposure to moisture are key.
- Mistakes such as rusting or sticky residue can often be reversed by re-seasoning or using coarse salt for cleaning.
- Cast iron cookware is highly durable and can last indefinitely with proper care, offering a non-stick surface that improves with use.
2. 🎨 Caring for Enameled Cast Iron
- Enameled cast iron can be cleaned by washing and scrubbing as usual with mild dish soap and avoiding abrasive cleaners, ensuring longevity and maintaining its appearance.
- The colorful enamel surface not only enhances the cookware's aesthetic appeal but also offers a protective layer that prevents rusting and eliminates the need for seasoning.
- Avoid using metal utensils to prevent chipping the enamel, and ensure the cookware is completely dry before storage to prevent moisture-related damage.
- For stubborn stains, a paste of baking soda and water can be used gently, avoiding vigorous scrubbing to maintain the enamel's integrity.
3. 🧽 Cleaning Plain Cast Iron
- Rinse and scrub the pan under hot tap water after every use to remove food residues.
- Use a long-handled scrub brush, such as the O-Cedar scrub brush, to keep hands safe from hot water and avoid burns.
- Hold the pan with a pot holder while scrubbing to further prevent burns.
- Avoid putting cold water in a hot pan to prevent thermal shock and potential damage.
- While soap is not required, a small amount can be used if desired, but never soak the pan or use excessive soap.
- After washing, dry the pan thoroughly with a towel or place it on a stove over low heat to ensure all moisture evaporates, preventing rust.
- Re-season the pan if necessary by applying a thin layer of oil and heating it to maintain its non-stick surface and prevent corrosion.
4. 🌡️ Drying and Oiling
- Dry the pan completely after washing to prevent rust.
- Place the pan back on medium heat to ensure it's fully dry.
- Add 1/4 teaspoon of vegetable oil to the pan.
- Use paper towels to wipe the oil around, holding with tongs if necessary.
- Continue wiping until it appears that the oil is wiped off.
- Heat the pan briefly until it is warm, which might produce smoke.
- Allow the pan to cool in place after heating.
5. ⚙️ Handling Stuck Food and Rust
- Add vegetable oil to about 1/4 inch deep on the pan and heat it on medium to loosen stuck food and rust.
- Remove the pan from heat, add a handful of kosher salt, creating a natural abrasive.
- Use tongs and paper towels to scrub the surface, as the mixture acts like an exfoliant and moisturizer, effectively removing residue.
- Repeat the process as needed for thorough cleaning, ensuring the pan is free of stuck food and rust.
- For persistent rust, consider using a steel wool pad along with the oil and salt mixture for more aggressive scrubbing.
