Puff Pastry Retash

The other day I was looking for something so delicious to cook and found it in the dishes of Hungarian cuisine. I liked the culinary recipe of an amazing puff pastry Retash right away. Cooked very easily and quickly! And the most delicate puff pastry with berries pleased me and my loved ones with a bright taste!
First I sifted flour, added an egg, 50 grams of melted lard, vinegar and warm water to it and kneaded a not too steep dough. Then I divided the dough into two parts, rolled up the balls, covered them with clean napkins and left them for a quarter of an hour. After that, I rolled out both balls, smeared them with lard, rolled them into four and left them in the refrigerator. After a while, I rolled out this dough. So I kept the dough in the refrigerator 3 more times and then rolled it out. Then she rolled out the dough again and began to stretch it with her hands until it became soft and very thin, like a tissue paper. I dried such a stretched dough a little, sprinkled it with lard again, sprinkled with nuts, breadcrumbs, put berries on it, which I mixed with sugar beforehand. Rolled the dough with the filling in the form of a roll, smeared with beaten egg, put on a baking sheet and baked in the oven until golden brown.
The retash turned out to be extremely tasty!
