Würstel

Vienna sausage is a thin parboiled sausage traditionally made of pork and beef in a casing of sheep's intestine, then given a low-temperature smoking. The word Wiener is German for 'Viennese'. In Austria, the term Wiener is uncommon for this food item, which instead is usually called Frankfurter Würstl. In some European countries, cooked and often smoked wiener sausages bought fresh from supermarkets, delicatessens and butcher shops may be called by a name (such as in German or French) which translates in English as "Vienna sausage". Traditionally, they are made from cured pork, but in Eastern and Southern Europe, sausages made from chicken or turkey are more common; these are also sold in places with a significant population of people who do not eat pork for religious reasons. Wieners sold in Europe have a taste and texture very much like North American hot dogs, but are usually longer and somewhat thinner, with a very light, edible casing. European Vienna sausages served hot in a long bun with condiments are often called "hot dogs", referring to the long sandwich as a whole. A spiced, paprika-rich look-alike of Vienna sausage is known as debrecener.
