Best Potato Bread

Directions

1. Place potato and 1-1/2 cups water in a small saucepan. Bring to a boil. Reduce heat; cover and simmer until very tender. Drain, reserving 1/2 cup liquid. Mash potatoes (without added milk or butter); set aside.
2. In a large bowl, dissolve yeast in warm water. Add the milk, butter, sugar, salt, 4 cups flour, potatoes and reserved cooking liquid; beat until smooth. Stir in enough remaining flour to form a stiff dough.
3. Turn onto a floured surface; knead until smooth and elastic, about 6-8 minutes. Place in a greased bowl, turning once to grease top. Cover and let rise in a warm place until doubled, about 1 hour.
4. Punch dough down. Turn onto a lightly floured surface; divide in half. Shape into loaves. Place in two greased 9x5-in. loaf pans. Cover and let rise until doubled, about 30 minutes.
5. Preheat oven to 375°. Sprinkle lightly with additional flour. Bake 35-40 minutes or until golden brown. Remove from pans to wire racks to cool.
