1995, December 25, Two female students in the dormitory found in the fridge, mouse))) And there was a bit of sour yogurt and a couple eggs. In the freezer was a handful of berries frozen from the summer. Sugar and butter, scraped the bottom of the barrel the entire Dorm. So my friend was the first time I baked this pie. She's half German and the recipe was brought by her mother from her grandmother from Germany. The cake turned out awesome! And now, 20 years later, I baked this cake always a pleasure. My friend now lives in Germany. And when I bake a cake, be sure to call her on Skype and a virtual treat.
