Pumpernickel Rye Bread

To make this recipe in a stand mixer, combine all of the ingredients in the mixing bowl. Mix on low speed using the dough hook, scraping the dough down occasionally, for 10 to 15 minutes. Transfer the dough to a greased bowl, cover it with plastic wrap and a kitchen towel, and allow it to rise until doubled, about 1 hour.Grease a 9×5-inch loaf pan. Deflate the dough and turn it out onto a lightly floured surface. Flatten the dough into a rectangle, pressing down with your hands to pop any air bubbles. Fold the dough into thirds, rolling it slightly under your palms to form a loaf, and pinch the seam to seal. Place the dough into the loaf pan, seam-side down, cover it with a floured kitchen towel or greased plastic wrap, and allow it to rise again until doubled. Bake as directed.
