Börek or burek or byrek is a family of pastries or pies made in the Middle East and the Balkans. The pastry is made of a thin flaky dough such as filo with a variety of fillings, such as meat, cheese, spinach, or potatoes. A börek may be prepared in a large pan and cut into portions after baking, or as individual pastries. They are usually baked but some varieties can be fried. Börek is sometimes sprinkled with sesame or nigella seeds, and it can be served hot or cold.
