Filo

Filo (Greek: φύλλο; ) or yufka (Turkish: ) is a very thin unleavenedpastrydough used for making baked goods. Filo-based products are made by layering many sheets of filo brushed with oil or butter; the pastry is then baked.

The paper-thin form of modern filo was developed in the Ottoman Empire by the 15th century. During this period, it became the foundation for a variety of sweet or savoury pastries, such as baklava and börek, which further diversified in shape over the centuries. Commercially manufactured filo became widely available in supermarkets during the 1970s.
