What is a Griddle?
A griddle is a piece of cooking equipment. In the industrial world (e.g. restaurant kitchens), it is usually a flat plate of metal (usually made out of aluminium, stainless steel or cast iron) with some kind of heat source beneath it (gas, for example).
In the non-industrial world, and in traditional cultures, the griddle may be a stone or brick slab or tablet. It is used over an open flame, or on a stove, to cook many foods, including many flatbreads. It may be used with or without oil.
