You spice a cast iron pan by rubbing the pan with a somewhat thin coat of neutral oil (I stress a light coat of oil). NOTE: Use vegetable oils (canola, sunflower, etc.), shortening (like Crisco shortening) or lard for seasoning your cast iron pans. I recently experimented and revealed that food-grade coconut oil/butter also works wonderful.
Position the cast iron pan, the wrong way up, in the stove, with a layer of aluminum foil on the underside to catch some drips. Heat the pan for 30 to 60 minutes in a 300 to 500 degree stove. After completed, allow the pan cool to room temperature. Repeating this practice several times is suggested as it will help form a stronger "seasoning" attachment.
The oil fills the material and results in being fixed in them, as well as rounding off the peaks. Through seasoning a new pan, the cooking surface makes a nonstick quality because the formerly serrated and rough surface becomes flat. Also, because the pores are permeated with oil, water cannot seep in and form rust that might give food an rancid-taste. Your ironware will probably be somewhat stained at this stage, but a couple of frying jobs will help put the last touches on the treatment, and turn the metal into the rich, black color that is the symbol of a admirably-seasoned, well-used skillet or pot.
In no way put cold fluid into a very hot cast iron pot or oven. They're going to crack straight away!
Be careful when cooking with your cast iron pots on an electric oven, as the burners generate hot spots which can warp cast iron or merely cause it to crack. You'll want to preheat the iron extremely little by little when using an electric range and preserve the settings to medium or even medium-low.
Important:
Unless you use your cast-iron pans daily, they ought to be cleaned for a moment with a little soapy water and then rinsed and completely dried so that you can rid them of spare surface oil. If you don't do this, the excess oil will turn out to be rotten within a couple of days.
Commit to memory - On every occasion you cook in your cast iron frying pan, you're essentially seasoning it all over again by filling in the tiny pores and valleys that are part of the cast-iron surface. The more you cook, the smoother the exterior becomes!
