Byrek is a delicious pie very common in Albania and other Balkan countries. "Peta" is not the same as "pita." Peta is a dry, baked, very thin, tortilla-like dough. It soaks up a lot of moisture in this byrek recipe. If you can't get baked peta, and you don't want to make your own (it is a very time-consuming process!), you can use phyllo dough. However, then you must cut down on the milk/egg mixture significantly because the phyllo does not absorb nearly as much liquid as the peta does.
