Makes 4 loaves
Dissolve yeast in water. Add 4 cups flour. Beat into smooth dough. Let rise in the bowl in a warm place until doubled in bulk.
Add salt, caraway seeds, and remaining flour. Knead about 15 minutes on a lightly floured board.
Divide dough into four equal parts. Shape into loaves, and place in greased pans (9×5×3) to rise in a warm place until doubled in size.
Brush tops with cold water.
Bake 1 hour in a preheated 350° oven.
