For Iranians, this dish serves the purpose of cooling you down in the sweltering summers. As in Turkey, Greece and India, a yogurt dish of this sort is a staple on the table during every family meal. Iranians love to vary the content, often using beetroot or spinach in place of the cucumber. In the height of summer, this dish is virtually treated as a soup, so perhaps it is Iran’s answer to the Spanish gazpacho.
It should be served chilled and, on the hottest of occasions, with ice cubes to help it stay cool.
To serve (optional):1 large cucumber, coarsely grated
