What is "kissel"?

Kissel is a type of sweet and thick dessert drink that is popular in many Eastern European countries, such as Russia, Belarus, and Ukraine. It is typically made from a combination of fruit juice, sugar, and cornstarch, which are simmered together to create a thick and creamy texture. Kissel may also include additional ingredients, such as berries, cherries, or apples, to give it a more fruity and flavorful taste.
