An electric waffle iron works by heating up a waffle-patterned grid using electricity. Waffle batter is then poured onto the waffle iron, and the heat cooks the batter into a warm, crisp waffle.

A waffle iron is a cooking appliance with hinged metal plates, which is used to make waffles.

You pour waffle batter on a waffle iron and bring down the top.

The cast iron waffle maker, as opposed to teflon waffle makers in domestic settings, is primarily used in the context of a restaurant or the outdoors. The cast iron waffle maker does not use electricity and waffles will not adhere to a properly seasoned cast iron surface.
