This recipe is from my sister. When I was 13-14 years old She got this from her friend and we all together tried to bake it. I'll say just one thing -You can present it even to the most whimsical gourmet, he/she will love it without any doubts!
For the dough: 3 egg yolks, 250 gr grated of margarine, 250gr sour cream, 3 glasses of flour. Soft dough. Put it for 45-60 minutes in refrigerator.
For the stuffing: 3 egg white, 1 glasses of sugar beat up with mixer. Raisins, nuts (actually I prefer walnut, but on that moment I'd pistachios at home)
