Shchi

Shchi (Russian:щи;IPA: [ɕːi]) is a Russian style of cabbage soup. When sauerkraut is used instead, the soup is called sour shchi, while soups based on sorrel, spinach, nettle, and similar plants are called green shchi (Russian:зелёные щи, zelyoniye shchi). In the past, the term sour shchi was also used to refer to a drink, a variation of kvass, which was unrelated to the soup.
