Ouzo is an aniseed-flavored liquid that hails from Greece. It is a popular alcoholic drink in Greece and is often served as an aperitif before meals. Ouzo is made from a combination of anise, star anise, coriander, fennel, and other herbs and spices. It has a distinctive aniseed flavor and is typically served with water and ice, which causes it to turn milky white. Ouzo is also sometimes used in cooking, particularly in dishes that call for an aniseed flavor.
