Kaalikeitto is the Finnish for "Cabbage soup". Kaalikeitto refers to a kind of soup made of vegetables like cabbage, onions, and carrots with a beef broth and chunks of beef in it. Kaalikeitto is mostly served in Finland on cold winter nights with a slice of sourdough bread. Kaalikeitto is also described as a clear, thick and flavourful soup made with white cabbage, root vegetables, stock and spices which is Russian in origin. Sauerkraut may be used to make the soup instead of the usual fresh cabbage.
