The use of cast-iron for cooking goes back over 2500 years albeit in Europe countries such as the UK have only used it for about 1000 years after it became popular when folk realised that complete pots with handles could be made using molten metal poured into moulds made out of sand. Originally these pots came with three legs as they were to be used on the open fire.

Seasoning cast iron cookware
It must be seasoned to protect the metal from rusting and to provide a non-stick surface. This is a straightforward process which once done shouldn’t need redoing. There are many good articles explaining this process but in summary it comprises of a simple 3 step process:
Cleaning the cast iron cookware back to its original surface;
Applying a layer of fat all over [typically fats high in saturated fats such as: Crisco, Palm oil, Coconut oil and lard]; then,
Heating up the ‘fat covered cookware’ to a high temperature causing the fat to bond to theiron.
Thereafter ongoing seasoning occurs as your cooking deposits evermore fat on top of the cured surface, giving it that lovely non stick dark glossy hue that characterises well-seasoned well-aged cast iron cookware.
If your cookware develops rust spots, scour the rusty areas with steel wool, until all traces of rust are gone then wash, dry and once again repeat seasoning process.
Cleaning the cookware
A lot of nonsense is talked about cleaning cast iron cookware; but the basics are straightforward:
Do not soak them or scrub them with scourers or anything metal;
Avoid strong cleaning products;
Wash with mild soap and water and dry with a paper towel then
Re-apply a thin layer of fat.
Never store food in the cast iron pan as the acid in the food will breakdown the seasoning and take on a metallic flavor
Types of cast iron
There are many brands of plain and enameled cast iron coming from around the world. Our advice at the Outdoor Cooking Equipment Store is go for the traditional black iron as the price differential, given the limited additional benefits of enamelled iron does not warrant paying so much more.
Enamelled pots also do not offer the benefits of standard cast iron such as the ability to withstand searing heat, the leaching of dietary iron and it never enjoys that beautiful black hue.
