"The sausage was invented by a butcher from Frankfurt, who had moved to Vienna, which is why in Vienna the sausage is called Frankfurter.
In some European countries, cooked and often smoked wieners 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". Wieners sold as vienna sausage in Europe have a taste and texture very much like North American "hot dogs" or "frankfurters", but are usually longer and somewhat thinner, with a very light, edible casing. European vienna sausage served hot in a long bun with condiments is often called a "hot dog", harking not to the wiener itself, but to the long sandwich as a whole.
In North America, the term "vienna sausage" has most often come to mean only smaller and much shorter smoked and canned wieners, rather than hot dogs." - wiki
Do you mean the longer hot dogs or the smaller cocktail weiners, and what are they made out of???
