Smørrebrød

Smørrebrød , smørbrød "butter bread" (Norwegian), or smörgås "butter goose" (Swedish), is a traditional open-faced sandwich in the cuisines of Denmark, Norway and Sweden that usually consists of a piece of buttered rye bread (rugbrød, a dense, dark brown bread), topped with commercial or homemade cold cuts, pieces of meat or fish, cheese or spreads, and garnishes. Bread is a very important part of the Scandinavian diet, primarily rugbrød, which is sourdough rye bread. It is a dark, heavy bread which is often bought sliced, in varieties from light-coloured rye to very dark, and from refined to whole-grain. Some toppings are served on franskbrød ('French bread'), a very light, crusty wheat bread. The bread is usually buttered, though for some variants, a spread of lard is customary. Traditional toppings include pickled herrings (plain, spiced or curried), slightly sweeter than Dutch or German herrings; thinly sliced cheese in many varieties; sliced cucumber, tomato and boiled eggs; pork liver-paste; dozens of types of cured or processed meat in thin slices, or smoked fish such as salmon; mackerel in tomato sauce; pickled cucumber; boiled egg, and rings of red onion. Mayonnaise mixed with peas, sliced boiled asparagus and diced carrot, called italiensk salat ('Italian salad'), remoulade or other thick sauces often top the layered open sandwich, which is usually eaten with utensils. It is custom to pass the dish of sliced bread around the table, and then to pass around each dish of toppings, and people help themselves.
