Pie iron

In the U.S., the Tostwich is possibly the earliest toasted sandwich maker, dating back to before 1920.

[1] Modern versions of the pie-iron are commonly more domestic, if not necessarily more refined, with subdivisions allowing pairs of bread slices to be clamped together around fillings to form pockets or stuffed sandwiches.

Campfire versions are still made of cast iron and can be cooked over coals, open flames, or a stove, but lightweight aluminium stove-top versions are made, generally being coated with a non-stick surface (PTFE) both as a cleaning aid and to allay fears regarding aluminium in the diet.

PFAs Once the device is hot, the sandwich can be assembled "inside-out", where the buttered side of the bread faces outwards against the metal plates and the filling sits inside.

[13] However, since the introduction of the Breville Snack'n'Sandwich Toaster in 1974, most electric jaffle makers in Australia split the sandwich in half.
