Kharcho has an exceptionally rich flavor as a result of the spice mix that is used to make it. Tradition says that lamb or beef is used in this soup. Therefore, it is comforting and rich. Tkemali is traditionally added as a sour plum sauce to balance out the richness of the soup. It can also be substituted with tomato puree or red wine vinegar. This delicious soup is the perfect dish for a cold, wintry day.
