Milwaukee Rye Bread - cooking recipe

Ingredients

4 potatoes - peeled, boiled and mashed
3/4 cup cornmeal
3 cups water
1 1/2 tablespoons salt
1 tablespoon white sugar
2 tablespoons shortening
1 (0.6 ounce) cake compressed fresh yeast
1/4 cup warm water (110 degrees F/45 degrees C)
6 cups rye flour
2 cups whole wheat flour

Preparation

In a small saucepan, cover peeled potatoes with water. Bring water to a boil and cook until tender, about 15 minutes. Drain and mash; let cool. In a separate sauce pan, stir the cornmeal into the 3 cups water. Bring to a boil and cook for 2 minutes. Stir in salt, sugar and shortening. Let cool to lukewarm.
In a large bowl, dissolve yeast in warm water. Add cooled cornmeal mixture and 2 cups of the cooled mashed potatoes. Stir in the rye flour and whole wheat flour 1 cup at a time; beating well after each addition. When the dough has pulled together, turn it out onto a lightly floured surface and knead until smooth and elastic, about 8 minutes. Lightly oil a large bowl, place the dough in the bowl and turn to coat with oil. Cover with a damp cloth and let rise in a warm place until doubled in volume, about 1 hour.
Deflate the dough and turn it out onto a lightly floured surface. Divide the dough into three equal pieces and form into loaves. Place the loaves into three lightly greased 9x5 inch loaf pans. Cover the loaves with a damp cloth and let rise until doubled in volume, about 40 minutes. Meanwhile, preheat oven to 375 degrees F (190 degrees C).
Bake in preheated oven for 60 to 70 minutes, until loaves sound hollow when tapped on the bottom.
