I have posted about koupes last month and you can see the original recipe here. The recipe for the dough is exactly the same. However, as the Orthodox have big lenten periods, fifty days before Easter, forty days before Christmas and some days before the Annunciation of the Virgin Mary as well as on some other occasions, we do not eat any kind of meat or fish, or animal products such as eggs, milk and subsequently products made with milk or eggs.
As the original recipes for koupes were stuffed with ground meat, during lenten periods we stuff them with mushrooms and believe me they are much better.
The collage is the same as for the meat koupes as the procedure is exactly the same.
