Futoški kupus is a traditional type of Serbian cabbage originating from Futog in Vojvodina. It comes in fresh or sour versions (although it's mostly designed for souring), and the cabbage has been cultivated in Futog from the 18th century onwards.
The leaves are thin, elastic, and flexible, and the texture is softer than other cabbage varieties in the wider region. When soured, after the fermentation, the head of the cabbage has amber-yellow color and a slightly oblate shape, while the leaves are slightly ellipsoid.
