Yogurt, Garlic, Cucumber and Fennel Dip

IN THIS fresh-tasting dip, the cooling taste of yogurt complements the bite of the garlic. Enjoy it with carrot sticks and other raw vegetables or with chips or crackers, or serve it with fried vegetables, like Fried Sun-Dried Tomatoes. Brought to Greece by the Turks, tzatziki seems to have its roots in Persian cuisine. In its more common form, it is made with only cucumber, but this version includes shredded fennel.
