I think this pie many will remember. For example, for us, this cake was very available for all ingredients when money was difficult. I lived with an aunt, she was holding a large farm, on the eggs, sour cream, cream – all this was in excess.. Well, the jam, the jam especially, all of his harvest. The cake is usually cooked on a currant or blueberry jam, of course if it was not, then any other jam was in the course. Also, instead of sour cream (cream), used yogurt. If the cake cut into cakes and add cream dipping, you get a juicy cake. In principle, in this form it was called "Rotten tree stump" or "Nigger in the foam".
