In a bowl pour the flour, add the grated butter, sour cream, sugar, soda and cold water. Knead dough. Refrigerate for 30 minutes.
Roll the dough. I must warn you: working with him is not very fun. It sticks to your hands and is difficult to roll out. I'm doing this directly on the parchment paper. Peel the apples and cut into plates. Spread on the dough.
Apples sprinkle with sugar and cinnamon and wrap the edges of the dough, as in the photo.
Transfer the cake into the mold. On apples posting a bit grated butter. Put in the oven for 30-35 minutes at a pace. 180-200 degrees. Remove from oven, sprinkle with powdered sugar and decorate. I have cranberries.
