Seasoning Cast Iron
Seasoning keeps the food from sticking to a cast iron cooking surface by filling in and smoothing out the roughness that we can’t see with the naked eye.
To season your cast iron, coat it evenly with a thin layer of shortening and bake it at 300˚F for 30 minutes. Pour off any excess liquid fat, and continue baking for 2 hours. Cool the pan upside-down on a stack of newspaper. The first few times you use the pan, use a lot of oil to continue the seasoning process. You can also repeat the seasoning steps a couple more times for a really good seal. Seasoned pans should never be scrubbed, as this would remove the oiled coating and expose new crevices for food to stick to. A light wipe with warm water is sufficient cleaning. This gentle cleaning also prolongs the life of the pan.
