Ingredients

The following products are needed for preparation:

• butter – 200 g;
• eggs – 3 pcs.;
• sugar – 1 glass. ;
• sour cream – 100 g;
• salt – a pinch.

How cook

Grate the butter into crumbs. Mix with 2 cups of flour. To make the butter easier to grind into crumbs, you can freeze it a little.

Mix three egg yolks and 100 g of sour cream. Add a pinch of salt and mix with the flour mixture. Now you can knead the dough.

Make walnut-sized balls from the dough. Put in the refrigerator for several hours. While the dough is cooling, you need to process the egg whites.

Whisk 3 egg whites together with sugar until thick peaks. Take a few balls out of the fridge and roll very thinly. Put a teaspoon of egg whites (filling) and fold as if you were gluing the dumpling. In the middle, press lightly with your finger to make a groove. And just fold the two halves over it, but you don't need to press anything. It is necessary to bake for 10-15 minutes at a temperature of 190 degrees.
