Kunafa roll with pistachio filling (Mabruma)

Prepare the syrup by combining water, rose water, sugar, and lemon juice in a saucepan. Bring to a boil and let it boil for 4 minutes. Then let it cool aside.
Prepare the filling by mixing the coarsely chopped pistachios with rose water and powdered sugar in a bowl. Stir until the nuts are evenly coated. Then, toast the mixture in a dry frying pan for a few minutes until the nuts are lightly toasted. Let the filling cool.
Preheat the oven to 220°C. Grease a large baking tray with a little butter.
Pull out the kunafa strands along the tray and repeat with the rest of the dough. Lightly grease each piece with butter.
Spread the pistachio filling along the length of each piece. Then roll the dough around the filling to create rolls.
Grease the rolls with the remaining butter and bake in the preheated oven until golden brown, about 15-20 minutes.
When the rolls are done, take them out of the oven and let the butter drain off. Then dip the rolls in the prepared syrup and let them soak for a few minutes.
Remove the rolls from the syrup and let excess syrup drain off. Place the rolls in the freezer for about an hour to set.
Take the rolls out of the freezer and cut them into smaller pieces. Serve cold and enjoy!

Note that you can use other types of nuts and margarine of your choice.
