Adding oil to old cast iron cookware is perfectly acceptable and can actually help improve its seasoning and non-stick properties. While dry cooking methods like using a seasoned cast iron pan without any additional oil are commonly recommended, adding oil can offer several benefits.
When you add oil to a cast iron pan, it helps create a natural non-stick surface, prevents food from sticking, and aids in even heat distribution. The oil also helps protect the cast iron from moisture and helps maintain the seasoning.
To properly use oil with cast iron, follow these steps:
Preheat the pan: Place the cast iron pan on the stove and preheat it over medium heat for a few minutes. Heating the pan helps open the pores of the metal, allowing the oil to be absorbed more effectively.
Apply oil: Once the pan is heated, you can add a small amount of oil to the pan and spread it evenly across the surface, including the sides. You can use a brush or a paper towel to apply the oil.
Heat and cool: Let the oil heat for a minute or so, ensuring it spreads evenly. Then, you can proceed with your cooking. After cooking, allow the pan to cool down naturally before cleaning it.
Clean and maintain: After cooking, clean the cast iron pan using mild soap and warm water, if necessary. Avoid using harsh abrasives that can strip away the seasoning. Once cleaned, dry the pan thoroughly to prevent rusting. Applying a thin layer of oil after cleaning can help maintain the seasoning and protect the pan.
Remember, the seasoning on cast iron develops and improves over time with regular use and proper maintenance. The oil you apply during cooking helps contribute to this seasoning layer, making the pan more non-stick and enhancing its performance.
Using oil in old cast iron cookware is a personal preference, and some individuals may choose to cook with minimal or no oil. However, incorporating oil into your cooking routine can help maintain and improve the quality of your cast iron cookware.
