# Prepare the syrup at first: Boil the mixture of water and granulated sugar
over medium heat. When, the mixture becomes thicker, add lemon
juice in it. Boil it for 5 more minutes. Then, remove it from the stove.
# Remove the flaked pastries from the freezer and let them soften at room temperature. Meanwhile, prepare the filling of the dessert. Remove the seeds of the dates and chop the dates over the bench finely. Add pounded walnut
and egg whites on it and mix.
# Cut the softened flaked pastry into 4 pieces. Roll them out a little by your fingertips. Place enough mixture of date onto the angled side of each triangle. Close the other side over this filling firmly.
# Repeat the same processes for all of the flaked pastries. Place the prepared pieces onto the greased baking tray with some spaces between them. (40 pieces, in total)
# Spread yolk all over the prepared pieces in the tray. Place the tray into the oven, which is preheated to 392 F.
# When the upper sides of the dessert pieces turn into red, remove the tray from the oven. Pour cold syrup all over the dessert urgently, after removing it from the oven.
# Serve it for about 2-3 hours later.
