@temujin77: Intestines. There are some specialities in Vorarlberg with Intestines. Includig lots of Sauerkraut.
The first time I ate Frog legs I was in Texas (strange enough). Pig feet and ears I have seen in various states of America in Gas Stations. But I never had the stomach to try it. My Grandfather likes them. But he puts dog into the Gulasch. So he may not be the best example.
