'Season' cast iron meaning
Seasoning cast iron means adding a layer of high quality oil to the surface. Doing this adds a nice “patina” to the surface of the cast iron pan.
Clean your cast iron pan. If seasoning a pan for regular use, make sure all food particles have been removed and the pan is dry.
Dry your cast iron pan. Wipe well with a paper towel or clean cloth towel and place in a warm (200-degree) oven for about 5 minutes to ensure it is completely dry.
Preheat your oven to 400-450 degrees. The general rule of thumb is to preheat your oven about 25 degrees above the smoke point of the oil you are using.
Apply a thin layer of your oil of choice to all pan surfaces (it should look shiny but not have a lot of texture; applying too much oil will lead to uneven absorption).
Place your pan upside down in the oven as it continues to preheat and bake for 60 minutes.
Remove the pan from the oven and allow to cool completely before storing.
