It is a soup originally from the Friuli cuisine, but that in the most famous version of Trieste is based on sauerkraut (in dialect, triestino capuzi garbi, acid caps), beans and potatoes; It is flavored with ribs, pork rind or other pork, smoked or not, and cumin seeds.
Many of its variants, including Carnia, Gorizia, Carsolina and Bisiac, which increase the amount of beans, or reduce it with the addition of barley or corn, replace all or half of the sauerkraut with brovada or add yellow flour to polenta.
