The practice of stretching raw dough into paper-thin sheets probably evolved in the kitchens of the Topkapı Palace, based on Central Asian prototypes.Yufka may have been "an early form of filo" since the Diwan Lughat al-Turk, a dictionary of Turkic dialects by Mahmud Kashgari recorded pleated/folded bread as one meaning of the word yuvgha, which is related to yufka, meaning 'thin', the modern Turkish name for phyllo as well as a Turkish flatbread also called yufka.
Prepared phyllo (also named kori) served with cheese in Bitola, Republic of Macedonia.
Filo dough is made with flour, water, and a small amount of oil and oscet or vinegar, though some dessert recipes also call for egg yolks. Homemade phyllo takes time and skill, requiring progressive rolling and stretching to a single thin and very large sheet. A very big table and a long roller are used, with continual flouring between layers to prevent tearing.
Machines for producing filo pastry were perfected in the 1970s, which have come to dominate the market. Phyllo for domestic use is widely available from supermarkets, fresh or frozen.
Filo can be used in many ways: layered, folded, rolled, or ruffled, with various fillings. Some common varieties are with:
Su böreği in Turkish cuisine consisting of boiled dough layers with cheese in between can be described as a salty version of baklava. Some recipes also use an egg yolk glaze on top when baked, to enhance color and crispness. In Western countries, filo is popular with South Asian immigrants in making samosas. Filo is used in many of the cuisines of the former Ottoman Empire; to make flaky pies and pastries, including baklava, börek, gözleme, spanakopita, tyropita and bstilla. Filo is also used for güllaç, a Turkish dessert mostly eaten in the holy month of Ramadan, where layers of walnuts and rose water are placed one by one in warm milk. A similar Egyptian dessert is called Umm Ali.
Filo is known by a variety of names in ethnic and regional cuisines. Among them are:
In Albanian cuisine, filo is called petë (plural) and the pies made out of it pite (mostly in Kosovo) or byrek, depending on the region and dialect spoken. Other types of pastries made out of filo, such as baklava, have various other names.
In Bosnia and Herzegovina, Croatia and Serbia, dough is called jufka while phyllo leaves are called kore (pl.). Pastries have various names, depending on mode of preparation. Gibanica is a speciality using kore and features white cheese and eggs.
In Bulgaria, the dough is called kori za banitsa (pl.) and the generic name for the pastries is banitsa, although there are special names for some specific kinds.
