Frankfurter Würstchen
Frankfurter Würstchen ('Frankfurt sausage') is a thin parboiled sausage in a casing of sheep's intestine. The flavour is acquired by low temperature smoking. For consumption, Frankfurters are occasionally heated in hot water for only about eight minutes to prevent the skin from bursting. If they are grilled, Frankfurt sausages are heated over propane or charcoal flame. They are traditionally served with bread, mustard, horseradish or potato salad.
