Kapusta [kah-POOS-tah], the Polish an the Slovak word for cabbage, is a popular dish in Polish cooking and Slovak cooking. Its primary ingredient has been pickled into sauerkraut and, in some places, kapusta simply refers to this plain sauerkraut. But in many other homes, this base is frequently amplified with a mix of mushrooms and onions, and that is what is meant by the term kapusta. Some cooks also add meat (usually pork, either rib meat or bacon),, resulting in what is often called bigos.
