Try sauerbraten

Sauerbraten is a traditional German roast of heavily marinated meat. It is regarded as a national dish of Germany, and is frequently served in German-style restaurants internationally. It can be cooked from a variety of meats, most often from beef, but also from chicken, lamb and mutton, pork and horse. Before cooking, the raw meat is marinated for 5 to 15 days in a mixture of wine or vinegar, water, herbs, spices, and seasonings. Usually, tougher cuts of meat, such as rump roast or bottom round of beef, are used, and the long marinating tenderizes the meat. A Sauerbraten dinner is almost always accompanied by a hearty gravy resulting from its roasting and is most often served with potato pancakes (Kartoffelpuffer), potato dumplings (Kartoffelklöße), or Spätzle.
