Sauerkraut is fermented cabbage. Sauerkraut is an excellent source of vitamin C and is commonly eaten with Hungarian kolbas, salami or csabai sausages. Sauerkraut is generally consumed as part of traditional dishes like stuffed cabbage or szekelygulyes (which a lot of people think is from Transylvania, because the Szekelysare from there, but in fact the dish is named after the author Joseph Szekelys, who is from Budapest).
