Iced Cucumber, Prawn & Yogurt Soup

Cacik is the Turkish word for a lovely salad made from diced cucumber, garlic and fresh mint leaves, seasoned and turned in yogurt. The same mixture is called tzatziki in Greek. If you thin it with a little iced water and add some prawns, you will have a delicate chilled soup which is as light and refreshing as it is quick and easy to make. Imported Greek yogurt is the nicest type to use for this dish.
