A Food Network chef gives the low down on seasoning a cast iron pan. Cast iron pans need to be seasoned before use because it will make your pan stick resistant and last a lifetime. Another plus of seasoning your cast iron pan is that you will not have to use any additional oil when you are cooking. The cast iron is a great heat conductor and the whole pan heats evenly instead of just in spots. To season a cast iron pan you will need to take a neutral oil, vegetable oil works fine, and rub it into the pan. Start out with a light coat. Then you bake your pan as directed in the video. Repeating this process a few time will season, or cure, your pan even more.
