Cast iron skillets are very durable, very heavy and disperses the heat very well. With it you can cook on high heat, in the oven, on the stove top, in the grill or basically anything that emits heat. When you buy a new cast iron cookware it has to be seasoned well. The standard procedure is to clean it very well, dry it very well, coat it with some vegetable oil and bake it in a 300 degree F. oven for about an hour. After that, just wipe the excess oil, if any, and the skillet is ready. The best part is, that you don’t have to clean it. Just put some salt in it, scrub it a little bit, wipe it and store it. After a few uses an excellent nonstick layer will form and you can even cook eggs in it.
