Oil Considerations For Cast Iron Cooking

Smoking Point

The smoking point of cast iron is a point of no return. It means that the oil has changed from a cooking base to burning in the bottom of the pan. Burning becomes a problem because it changes the oil composition and releases things called free radicals or toxic fumes. No one wants to inhale or cook food with something that has entered the toxic zone.

In order to keep you and the food you are putting into your body safe, choose an oil that matches the temperature zone used for cooking. Extra-virgin olive oil has a relatively low smoke point, around 375 degrees. However, light or refined olive oil's smoke point is around 465 degrees. Avocado oil has the most tolerant smoke point at 520 degrees.

Flavor

Depending on the dish, it may depend on the choice of oil for the meal. Asian cuisine may require peanut or sesame oil to imbue a certain palate. However, sometimes a more neutral flavor is called for. Oils like soybean, canola, sunflower, or refined olive are all known for their neutral flavors.

Easy Clean-up

Clean-up the kitchen with ease after cooking with cast iron. Wiping out the skillet with a clean cloth or paper towel is the first step. Afterwards, rinse with water and a little bit of vegetable-based soap for the truly tough and stuck-on spots.

Also, when cooking, make sure to add oil or butter to the pan in an appropriate amount. Many recipes call for one to two tablespoons of oil because of the nutrients it provides for our bodies.

How often should you season cast iron skillet?

Perpetual seasoning of cast iron will keep everything in check. Seasoning cast iron means that oil has been baked into the pan, creating a surface that food will easily slide out of. As cast iron gets used over time, seasoning creates a darker surface that becomes effortless for cooking and cleaning.

If seasoning cast iron at home, use an oil with a high smoke point to coat the pan. Put a baking sheet or another dish larger than the pan on the rack below it in the oven. Then, take the cast iron, turn it over on the rack, and bake it in the oven for one hour. Cast iron holds up to heat, so it has a significant range. Heat to at least 350 degrees, but up to 500 degrees for seasoning. Once the hour is over, turn the oven off and allow the cast iron to cool on its own before removing it. Over time, this process creates an easier work surface. For more information on how often to season cast iron, click here.

Olive oil is a great oil to use on food, but unless it is the light or refined kind, its smoke point is comparatively low. Avocado oil's smoke point is around 520, the highest. Canola and vegetable oil have smoke points around 425-450 degrees.

What should you not cook in cast iron?

Cast iron properly seasoned over time works wonders with any recipe. If the cast iron is new or newly seasoned, consider avoiding or reducing the number of acidic foods that may make it difficult to retain that shiny, smooth cast iron surface. Acidic foods are things like tomatoes, citrus, or vinegar.

If the cast iron recently came home from the store, or it hasn't been seasoned multiple times, consider waiting to cook eggs or fish. Cast iron pans do great with these types of foods, but not until after some seasoning has taken place.
