Iron & Cast Iron Care

Iron and cast iron cookware can last a lifetime and even be passed down to future generations if cared for properly. Here's how to maintain them to ensure they remain functional and beautiful:

1. Seasoning Your Cast Iron:

Seasoning is crucial for cast iron cookware. It creates a natural non-stick surface and protects the metal from rust.

  • Initial Seasoning: When you first get a cast iron pan, wash it with warm, soapy water to remove any factory residue, then dry it completely. Apply a thin layer of neutral, high-smoke point oil (like flaxseed, vegetable, or canola oil) all over the pan (inside and out). Place the pan upside down in the oven at 375–450°F (190–230°C) for an hour. Let it cool completely in the oven. Repeat this a few times for the best results. Heating can be done on stove top on medium heat, although an oven will heat the cookware more evenly.
  • Maintaining Seasoning: After each use, apply a thin layer of oil to maintain the seasoning. Avoid using too much oil, as it can create a sticky surface.

2. Cleaning:

  • Avoid Soapy Water: After cooking, you may avoid soap, as it can strip away the seasoning. Instead, use hot water and a stiff brush or a soft sponge. If there’s food stuck to the surface, use coarse salt as a natural abrasive to scrub the pan. If you must use soap, use a mild and natural one and re-season it by heating it and applying a thin layer of oil on the surface.
  • No Dishwashers: Never put cast iron in the dishwasher. It will strip away seasoning and can cause rust.
  • Dry Immediately: After washing, dry the cookware thoroughly. Cast iron is prone to rust, so ensure it’s completely dry, either by towel drying or placing it on low heat for a few minutes.

3. Preventing Rust:

  • Dry Immediately After Washing: Don’t leave cast iron to air dry. Wipe it down thoroughly, then heat it slightly to ensure all moisture is evaporated.
  • Light Oil Coat: After drying, apply a very light layer of oil to protect the surface from moisture and rust. This will also maintain the seasoning.
  • Store in a Dry Area: Make sure your cast iron is stored in a cool, dry place. If you’re stacking cast iron cookware, place a paper towel between them to absorb any moisture.

4. Handling Rust:

  • Rust Removal: If rust appears, don’t worry! You can remove it by scrubbing with steel wool or a stiff brush, then washing, drying, and re-seasoning the pan.
  • Re-seasoning After Rust Removal: After removing the rust, it’s important to re-season the pan following the steps in the "Seasoning Your Cast Iron" section.

5. Using Cast Iron on Different Heat Sources:

  • Even Heating: Cast iron heats slowly but retains heat well. Always allow your pan to preheat on low to medium heat to avoid hot spots and warping.
  • Avoid High Heat: Avoid cooking on extremely high heat as it can damage the seasoning or cause food to stick. Moderate heat is sufficient for most cooking tasks.
  • Oven Use: Cast iron is oven-safe and great for baking. When using it in the oven, you may want to oil the handles to prevent rusting.

6. Cooking with Cast Iron:

  • Avoid Acidic Foods: While well-seasoned cast iron can handle acidic foods (like tomatoes or citrus-based sauces), long cooking times with acidic ingredients can erode the seasoning. If you cook acidic foods often, be sure to re-season afterward.
  • Non-Stick Cooking: Properly seasoned cast iron should be naturally non-stick. Always preheat the pan before adding oil or food to ensure a good non-stick surface.

7. Handling Cast Iron:

  • Heavy Weight: Be cautious of the weight, especially with large pans. When moving cast iron around, use two hands if necessary to avoid dropping it and causing damage.
  • Hot Handles: Cast iron handles get very hot. Always use oven mitts or a thick cloth when handling the cookware during or after cooking.

8. Long-Term Care:

  • Re-season as Needed: If you notice food sticking or the surface looking dull or patchy, it’s time to re-season the cookware.
  • Avoid Storing Food: Don’t store food in cast iron, especially acidic or moist foods, as this can affect the seasoning and potentially lead to rust.

9. Storing Cast Iron:

  • Dry, Cool Place: Store your cast iron cookware in a cool, dry area to prevent moisture buildup.
  • Liners for Stacking: If you stack cast iron pieces, place paper towels or cloth between them to absorb moisture and avoid scratching the seasoning.

By following these steps and maintaining your cast iron cookware regularly, you’ll keep it looking beautiful and ensure it lasts for generations. The more you cook with it, the better the seasoning will become, improving its non-stick properties and durability over time.
