Blueberry Vareniki or Blueberry Dumplings, Madd Russian Recipe

Roll out dough about 1/8 inch thick and cut into 3-inch circles with a glass or a cookie cutter. 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. Fold, seal ( put egg whites lightly beaten on the inside edge to help seal the vareniki )( I also fork the edge myself) Prepare the pan of boiling water for cooking the Varenikis. and cook in pot of salted boiling water as soon as you can (they are done when they float) gently remove from pot with a slotted spoon.. Cook in as needed. Serve HOT with sour cream for dipping. Best if one cooks and the others eat. My record in one sitting is 27 (:-)>)
