Yes, you can and should oil cast iron cookware. Oiling cast iron is a crucial part of both cooking and maintaining it. Here’s why and how:
Why Oil Cast Iron?
Oiling cast iron serves two primary purposes:
-
Preventing Food from Sticking: When cooking in cast iron, a thin layer of oil creates a barrier between the food and the pan's surface. This helps prevent food from sticking, ensuring easier cooking and cleaning.
- As the reference states: "you should add a little oil to the pan before adding your food. This helps ensure the food doesn't stick".
-
Building and Maintaining Seasoning: Seasoning refers to the layers of polymerized oil that create a non-stick surface on cast iron. Regular oiling, especially after cleaning, helps build and maintain this vital seasoning.
- As the reference states: "it helps build layers of seasoning".
How to Oil Cast Iron
There are a few key steps to properly oil your cast iron:
- Clean the Pan: After cooking, clean your cast iron pan while it's still warm with hot water and a gentle brush. Avoid using soap, which can degrade the seasoning.
- Dry Thoroughly: Dry the pan completely with a towel or by heating it on the stovetop. Any moisture left can cause rust.
- Apply Oil: While the pan is still warm, add a small amount of cooking oil to the pan. Spread the oil around with a paper towel or cloth, ensuring that it coats the entire cooking surface.
- Wipe Off Excess Oil: Wipe off any excess oil with a clean, dry cloth or paper towel. You should be left with a very thin, almost imperceptible layer of oil. Too much oil can lead to a sticky residue.
- Heat the Pan: Place the oiled pan on the stovetop over medium heat or in the oven at a low temperature for a few minutes until the oil is slightly absorbed by the pan and starts to smoke lightly. This process, called polymerization, helps the oil bond with the metal and forms the layer of seasoning.
- Cool Down: Let the pan cool completely before storing it.
Types of Oil to Use
The reference indicates that "You can generally use whatever oil you prefer, as long as the cooking temperature is below the smoke point of the oil." Here are some common oils used for seasoning cast iron:
- Vegetable Oil: A good all-purpose oil with a high smoke point.
- Canola Oil: Another versatile oil suitable for high heat cooking and seasoning.
- Grapeseed Oil: Known for its high smoke point and neutral flavor.
- Flaxseed Oil: This can be used for seasoning, but might flake over time and not be recommended for regular use.
- Avocado Oil: Also a high smoke point oil for cooking and seasoning.
- Animal Fats: Lard, bacon fat, or tallow can also be used, adding flavor and enhancing the seasoning over time.
Important Considerations
- Smoke Point: Be mindful of the smoke point of your chosen oil. Heating the oil past its smoke point can cause it to break down and produce an unpleasant smell or flavor, as well as potential damage to the seasoning.
- Consistent Maintenance: Regular cleaning and oiling are crucial for maintaining a well-seasoned cast iron pan.
- Avoid Harsh Cleaners: Never use harsh cleaners or scouring pads on your cast iron pan, as they can remove the seasoning.
By oiling your cast iron correctly, you will have a durable and reliable piece of cookware that can last for generations.
