Škembe čorba is a traditional soup made with a combination of tripe (usually pork or beef), onions, garlic, tomato sauce, bacon, and additional seasonings such as red pepper, black pepper, parsley, and bay leaves. The preparation process is notoriously long: tripe is first cooked separately for at least four hours, cut into thin strips, and then cooked again with the rest of the ingredients. Škembe čorba is typically served with vinegar, sour cream, and warm bread on the side.
