While the meat is boiling, prepare the dough. Pour the water into a bowl, add egg and salt while stirring. Add the flour and knead the dough. The ready dough should be divided into two equal parts and placed for 10-15 minutes under a dish. This procedure makes it soft and pliable for rolling. Make those 2 parts into a bun which is then flattened by pressing down on it. Keep covered with a linen cloth and left for 15 minutes.
