Tzatziki

This wonderfully refreshing sauce, dip, starter, call it what you will, is very versatile. It can be used as an accompaniment to simple lamb souvlakia (kebabs), spread on little squares of bread as a snack with your apéritif, or served as a dip to go with mixed, raw vegetables (crudités) such as crisp batons of carrot, celery, spring onion etc.
