Cast iron cookware tends to rust if not seasoned properly. While your cookware has been pre-seasoned, you will periodically need to re-season it to maintain its stick-resistant and rust-proof finish. This process allows oil to be firmly re-absorbed into the iron. Well-seasoned cast iron cookware has a black colour which is normal and to be expected. If food starts to stick to the interior surface or if rust is present, you will need to re-season your pan as follows:
- Make sure you have the right kind of oil for seasoning your pan. Some examples of seasoning oil are flaxseed oil, sunflower oil, canola oil or soybean oil.
- Remove all food residue and rust by thoroughly cleaning your pan with hot, soapy water and a nylon brush. You may warm the pan up slightly on the stovetop to make this process easier.
- Dry the cookware thoroughly; you can do this by heating the pan until the moisture on its surface evaporates, and then allowing it to cool naturally.
- If using a gas stove:
- Apply a very thin, even layer of seasoning oil inside the pan.
- Thoroughly wipe off all excess oil with a kitchen towel — the pan should look matte and feel dry, not greasy to the touch.
- Place the cookware on the gas stove.
- Preheat the pan gradually starting on low heat, increasing the temperature slowly to medium high. Proceed with caution, as high flames may cause excess oil to ignite.
- Heat the pan until oil reaches its smoking point and no remaining oil residue is left. Repeat the process at least 2-3 times.
- If using the oven:
- Apply a very thin, even layer of seasoning oil inside and out.
- Thoroughly wipe off all excess oil with a kitchen towel — the pan should look matte and feel dry, not greasy to the touch.
- Place the cookware in the oven upside down and directly on the middle oven rack.
- Place a large baking sheet or large piece of foil on a rack below to capture drips.
- Targeting the smoke point of your seasoning oil, bake between 350°F/180°C to 450°F/230°C for one hour.
- Allow the cookware to cool down before removing the pan to avoid any injury to yourself/your property. Always use potholders or pinch-grips while gripping the handle.
- Store in a dry place, placing paper towels between the pan and lid (if applicable) and other items to absorb moisture and prevent rusting.
- Note: It is best to repeat this seasoning process several times to ensure your pan is well seasoned. We also recommend cooking high-fat foods in your pan for the first few uses for further seasoning of the pan. Avoid long simmering of liquid (e.g. soup) or acidic food (e.g. tomatoes, vinegar, citrus) to protect your seasoning.
