A sandwich toaster (or toasted sandwich maker, also jaffle iron in Australia and South Africa, toastie maker in the United Kingdom and New Zealand {sometimes quixie iron or quicksie iron in New Zealand}; also sometimes known by the brandname Breville) is an electrical appliance used to toast sandwiches. Ordinary kitchen units generally consist of indented hot plates, clamped together around the sandwich. Usually two sandwiches can be toasted at a time. The plates are heated by electrical coils inside the appliance. Usually the exterior is somewhat separate from these to ensure the outside of the unit does not get too hot. The plates often clamp tightly around the edge of the sandwich, sealing in the filling. The use of a special sandwich toaster seals the edges of the sandwich and places a diagonal line across it, thus solving the problem of content spillage. Typical toasted sandwiches are a grilled cheese sandwich, tuna melt, or patty melt.Some of the earliest such sandwich toaster were made by Breville, still used as a generic term in some parts of the world. Toasted sandwiches are frequently known as a toastie in Britain, the older Breville (as a name for the sandwich) never having entered popular usage. In Australia, toasted sandwiches with sealed edges are sometimes called brevilles. In South Africa and Australia, toasted sandwiches with sealed edges are sometimes called jaffles, named after the original jaffle iron (U.S. English: "pie iron"), which was a long-handled hinged iron implement for toasting sandwiches in a campfire. Sandwich toasters are uncommon in the United States where grilled cheese sandwiches are more common.
