In a large bowl, dissolve yeast in warm water. Add the applesauce, milk, sugar, butter, salt, egg yolk and 2 cups flour; beat until smooth. Stir in enough remaining flour to form a firm dough. Stir in raisins and caraway seeds.
Turn onto a lightly floured surface; knead until smooth and elastic, about 6-8 minutes. Place in a bowl coated with cooking spray, turning once to coat top. Cover and let rise in a warm place until doubled, about 1 hour.
Punch dough down. Turn onto a lightly floured surface; divide in half. Shape each portion into a ball. Place 4 in. apart on a baking sheet coated with cooking spray. Pat into 6-in. round loaves. Cover and let rise until almost doubled, about 45 minutes.
In a small bowl, beat egg white and cold water; brush over loaves. Bake at 375° for 30-35 minutes or until golden brown. Cool on a wire rack. Yield: 2 loaves (8 slices each).
