A pie iron, also called a pudgy pie iron, sandwich toaster, snackwicher, pie burner, toastie maker, sandwich maker, or panini grill, 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 checkered pattern. Pie irons are used to heat, toast and seal the sandwich.
