Like so many other Greek specialties, bougatsa has a long history, in this case one that stretches all the way back to Byzantine times. Bougatsa is mainly a breakfast pie with a phyllo pastry made of flour, softened butter and oil that requires a great deal of skill to prepare. This pie is made and enjoyed all around Greece, but particularly famous are those made in northern Greece, especially in Thessaloniki and Serres. Turkish börek is a close relation, and similar pies are traditional to many eastern Balkan countries that were formally part of the Ottoman Empire. The tradition of bougatsa making really took off around Greece in the early 1920s with the arrival of the Greek refugees from Asia Minor and Cappadocia.
