Seasoning of cast iron

Cast iron cookware has a very effective non-stick coating if you make sure to build it up and maintain it.

It is possible to use other oils, but coconut oil works very well for this. If you use another type of oil, make sure to heat it up above its smoke point. The coating is made when the oil breaks down.

The non-stick coating on cast iron does not have the health issues that flouropolymer coatings has, like Teflon.
