Tarator was the name of a dish made of ground walnuts and vinegar in the Ottoman Empire. The preparation of Tzatziki is very ancient. Probably, this sauce has been created to use to excess of yogurt production. The word Tzatziki derives from the Persian zhazh, that means herb mixture. Recipes similar to Tzatziki are very popular in Middle Eastern countries, Greece, and Southern Balkans. In Turkey, Cacik is a variation of Tzatziki with Sumac spice, fresh mint, and water: served as soup or side dish. In Balkans countries, this sauce is named Tarator, and enriched with walnuts and sometimes minced onions. Tarator is also popular in Albania and often paired with grilled squid.
Mix all well and serve with Rotisserie Gyros.
