Börek (also burek, bourekas or boreg and others) is a family of baked filled pastries made of a thin flaky dough such as phyllo or yufka. Common fillings are made with meat, cheese, leafy greens (usually spinach) or potatoes. Börek are found in the cuisines of the Balkans, the South Caucasus, the Levant, Central Asia, and some Eastern and Central European countries. A börek may be prepared in a large pan and cut into portions after baking, or as individual pastries. Börek is occasionally sprinkled with sesame or nigella seeds.
