Yeast plum pie

Sow butter or margarine with flour. Pour yeast diluted in warm milk. Add the yolks, ground with sugar and vanilla sugar. Add sour cream and knead the lush dough. Roll out the cake, put it on an oil-greased baking sheet, grease the dough with protein. Put the pitted plums on the bark of the halves (with the skin to the dough). Leave the pie for an hour in a warm place so that the dough fits. Bake in a hot oven (200-220 ° C) for about 35-45 minutes. Remove the finished pie from the baking sheet, sprinkle still hot densely with vanilla sugar powder.
