Bread

Dough
Heat milk, butter, salt and sugar until melted together. Add yeast to 1/4 C and allow to stand for 10 minutes to proof. Allow the remainder of the milk mixture to cool. Beat egg yolks until foamy and add to cooled milk mixture. Add yeast mixture to remainder, then add 6 C flour. Mix gently with a spoon and let rise on a board until doubled, about 2 hours. Divide into 6 balls and let rise for 1/2-1 hour. Roll out on floured surface to 1/4 inch thickness. Spread with filling and roll, folding the ends under. Place on buttered cookie sheet and let stand about 15-20 minutes. Beat 1 egg with a little bit of water and brush on the tops of the rolls. Bake at 375 for about 30 mins.

Nut Filling
Mix walnuts, and sugar. Beat egg whites and fold into nut/sugar mixture. Add vanilla and mix well.

Prune Filling
Cover prunes in water and cook for about 30 mins. Drain, then add sugar and lemon juice and mix well.
