Add sifted flour to warm salted water. Knead dough and let stand 10-15 minutes. Roll out into a thin layer, 1 mm. Rub surface with grease, sour cream, or butter. Roll the dough around itself using a rolling stick (similar to a dowel). Cut lengthwise along the stick which will result in several layers of strips of dough. Cut into thinner strips 2 cm strips. Roll up each strip, place in its side and flatten with a rolling pin to a thickness of 1 cm. Coat frying pan with melted butter and fry on both sides.
