Crumble yeast cake into lukewarm milk to which 3 Tablespoon of sugar has been added. When dissolved, stir in 3 cups of flour. Beat it with a wooden spoon; let rise until double. In the meantime combine remaining ingredients, adding the eggs, one at a time, as you beat with electric mixer. When spongy dough has risen, combine the two mixtures, adding some plumped white raisins if desired. Place dough in 4 greased loaf pans. Top with crumbs. Let rise 45 minutes to 1 hour until light. Put in preheated 375° oven and bake 30 minutes.
