Turkish cuisine is famous for its endless varieties of delicious layered pies and pastries, called 'börek'. 'Börek' is made with layers of yufka or phyllo. It comes in many shapes and sizes and is filled with everything from meat, cheese, spinach, and even spiced-up mashed potato. Most Turkish folks eat 'börek' several times a week. That's why you'll find 'börek' in every home, pastry shop and bakery. Families often pass recipes and 'börek'-making skills down through generations, and everyone adds their own touch. What gives its name is one of the steps of the recipe instructions. Homemade phyllo sheets are cooked in simmering water and then stuffed and baked. That's why it's called su boregi (Water Borek).
