Abdug or Dugh: a refreshing tangy drink of yogurt diluted with plain or mineral water and lightly salted. Often served with meals or as a refreshment by itself. Abdug is also very popular in South Azerbaijan. This version of Azerbaijan's yoghurt soup has no rice and is served in the summertime with ice cubes. It may include raisins, chopped walnuts and rose petals. At the table, each person may add crushed dried, toasted lavash or paper-thin bread in the soup.
