Blueberry Vareniki recipe

Method :

Combine all the ingredients in the bowl of a electric mixer with the dough hook in place. Mix for 1 minute at low speed, then raise the speed to moderate and beat for 2 minutes; the dough should be well blended, smooth, and elastic. However you knead the dough, form it into 2 balls, dust lightly with all-purpose flour, cover tightly with plastic wrap, and allow to rest for 30 minutes. Roll out dough about 1/8 inch thick and cut into 3-inch circles. Prepare the pan of boiling water for cooking the varenikis. Just before filling the rounds, lightly toss the blueberries with the sugar and cinnamon. Spread on a plate and dust with the flour. Fill each round with a scant tablespoon of blueberries. Seal (using egg whites on the edge)and cook as soon as you can. Cook as needed. Serve hot with sour cream.
