The “Kanonenputzer” seems to be a bit hard to find! It's a giant sausage served up at a place called Restaurant Zeughauskeller in Zurich. Up to 1 metre long, it's all the meal you need when you're in the cold cold months of a Zurich winter!
Panfried sausage from the French-speaking region of Switzerland. Served in half-meter or meter lengths. The sausage specialty par excellence.
