Lithuanian Cabbage Soup

Kopūstų Sriuba (cabbage soup) is the Lithuanian winter staple, made when fresh vegetables are gone and the cellar holds sauerkraut (fermented cabbage), smoked pork, and root vegetables. The sauerkraut gives the soup its sour backbone; the smoked pork (often a smoked ham hock or ribs) gives it depth; the barley thickens it into a meal. This is the Eastern European peasant tradition at its most essential — preserving the harvest through fermentation and smoking, then turning those preserved foods into a sustaining winter meal. Every Lithuanian winter kitchen smells of this soup.

A bowl of cloudy, pale-gold soup with chunks of smoked pork, soft potato, shreds of sauerkraut, and the plump grains of barley. The taste is sour from the kraut, smoky from the pork, hearty from the barley. Eat it with dark rye bread, on a freezing January day. It is the warmest thing in Lithuania.

The sauerkraut is the flavor base — it is rinsed (to control the sourness) then simmered for an hour. The smoked pork (a hock or ribs) is simmered with it, releasing its smoky fat and tenderizing. Barley is added (it thickens the soup and makes it substantial). Root vegetables (carrot, onion) add sweetness. The long simmer (60+ minutes) melds the sour, smoky, and sweet into a single complex flavor.
