Source: The New McCall's Cookbook. This is wonderful (wonderbar?) German and Swiss-German specialty served with spaetzle (Swiss dumplings) or other dumplings, egg noodles or potatoes and red cabbage. When making this use a good quality wine and vinegar. They'll have an impact on your final product. Also, make sure the meat is nicely marbled and has a fat cap on the top and side to keep the roast moist while it's cooking. Cooking time includes 3 days marinating time. Posted for ZWT6
