Skābeņu zupa is a traditional sorrel soup. It is made with beef stock, chopped sorrel leaves, pearl barley, onions, potatoes, and lemon juice. Common additions include grated carrots and smoked pork ribs, while hard-boiled eggs and sour cream are typically used as garnishes.

Although skābeņu zupa is most commonly served warm or hot, it is very refreshing when served ice cold on hot summer days. The word skābeņu in the name of this soup is derived from skābs, meaning sour, referring to sorrel’s flavor.
