You may have seen eyebrows raised over Ouzo, a potent anise-flavored liqueur popular in Greece. But if you drink it "right" it can be a lovely experience.
Greeks generally drink Ouzo as an aperitif and they always have it with something to eat, such as nuts or other savory foods. It is most often served with ice, which turns the liquid cloudy, and a pitcher of water. The water is meant to be poured in to the Ouzo as you drink it to dilute it and make it last longer.
