Sorrel soup usually includes further ingredients such as egg yolks or whole eggs (hard boiled or scrambled), potatoes, carrots, parsley root, and rice.[1][2][12] A variety of Ukrainian green borscht also includes beetroot.[4] In Polish, Ukrainian, Belarusian and Russian cuisines, sorrel soup may be prepared using any kind of broth instead of water.[1][3] It is usually garnished with smetana (an Eastern European variety of sour cream).[1][3] It can also be a kosher food. It may be served either hot or chilled.
