In a bowl pour the flour and all dry ingredients - sugar, baking powder, slaked soda (soda can not add, then it is necessary to increase the amount of baking powder), salt. Put softened, but not liquid butter (a pack I split into two parts and put in the microwave for 20 sec), sour cream and egg yolks. Mix well.

I kneaded the dough in the bowl by hand.

Just refreshed it a bit the dough with food coloring yellow (1 Dec. L.). The dough was placed in a deep plate and put it in the fridge until morning.

The dough in the refrigerator frozen, hardened. During operation, it will become soft, sticky from the heat source and the temperature of the air, so it must be knead with flour. Split the dough in pieces and quite a bit rolled in flour, to not stuck to the hands. If the dough knead until then, until it takes the flour then the pastry will be more crumbly and will be good to keep the original form. Flour to add, then products will be more airy, soft and form rolls are spread out, as I have here. My goal was not to save the form rolls and to please all my men. Who doesn't like crumbling pastries or too airy, soft...

Made eight large buns. Pastry is not rolled out and flattened with your fingers, put four raisins in the other four raisins, cinnamon, sugar. The top is usually smeared egg or the yolk. These muffins I did not grease.

Put them for 30 minutes in a hot oven at 180 degrees. The buns turned out in a crisp and soft.

And this dough is the same but without the sour cream. The bread turned out crumbly.

Toppings - sour grapes. A good mix - the dough is sweet and sour filling. You can pour the grape sugar, but without him I like.

Filling - plum.

Sweet, crumbly pastry with juicy plums.

Sweet bun with sour grapes and juicy plums wonderfully complement each other.

And this shortbread cookies - very crisp with raspberries and strawberries.
