Shchi

Shchi is a Russian-style 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. 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.
