Using a stand mixer and a dough hook, combine 3/4 cup sugar, 2 egg yolks, 1 whole egg, 3 cups flour, 4 tbsps sour cream and 1 pinch salt to create a thick dough.
Divide the dough into 8 equal portions and roll out each portion individually on a cookie/baking sheet. Rolled out dough should be very thin and all rolled out portions should be relatively equal in size.
Bake each layer in a 400 degree preheated oven for about 5 or 6 minutes, or until edges begin to brown. Remove from the oven and set them aside to cool.
Once cool, crumble ONE of the layers into small crumbs to be sprinkled on top of the finished pastry.
