There is nothing better than cooking with Cast Iron! Cast Iron stays hot longer than most pans once heated up, heats and cooks evening and very easy to clean up.
I recommend seasoning the pans once in awhile. To season your cast iron, wash and dry your pan (I normally set in on a warm burner, cook stove or whatever you cook with and warm the pan until it is dry. Then spread a thin layer of shortening or lard. I also usually take a paper towel and wipe out any excess.
