Eisbein

Eisbein is a German dish of corned ham hock, usually cured and slightly boiled. Eisbein is usually sold already cured and sometimes smoked, and then used in simple hearty dishes. Numerous regional variations exist, for example in Berlin it is served with pease pudding. In southern parts of Germany it is usually roasted. In Franconia it is commonly served with mashed potatoes or sauerkraut, in Austria with horseradish and mustard instead. The German name has associations with the practice of using a pig's leg-bone for ice skating. In southern Germany, the common preparation is known as Schweinshaxe.
