A pie iron—also called pudgy pie iron, sandwich toaster, snackwicher, toastie maker, sandwich maker—is a cooking appliance that consists of two hinged concave, round or square, cast iron or aluminium plates on long handles. Its "clamshell" design resembles that of a waffle iron, but without the honeycomb pattern. Pie irons are used to heat, toast and seal the sandwich.
