Whole sour cabbage (Croatian: Kiselo zelje u glavicama, Serbian: Kiseli kupus u glavicama, literally: "cabbage soured in heads")[1] is a fermented vegetable food preserve, popular in Eastern European and Balkan cuisines. It is similar to sauerkraut, with the difference that it is prepared through the lacto-fermentation for several weeks of whole heads of cabbage, not separate leaves or grated mass. No vinegar or boiling is required. It is a homemade food preserve, commonly prepared in large barrels filled with whole cabbage heads and water salted with sea salt.[2]
