Sweet Potato Sourdough Bread
Yield : 1 loaf
1/2 Cup Active, Unfed Sourdough Starter
1/2 Cup Warm Water
3/4 Cup All Purpose Flour
1/4 Teaspoon Instant Dry Yeast
1 Cup Plain Mashed Sweet Potatoes (Peeled, Boiled, Mashed Smooth; Nothing Added)
1/4 Cup Plain Non-Dairy Milk
1 Teaspoon Salt
1/2 Teaspoon Ground Ginger
3 Tablespoons Olive Oil
2 Tablespoons Dark Brown Sugar, Firmly Packed
3 – 4 Cups White Whole Wheat flour
Combine the first four ingredients in a large, non-metallic bowl and blend well. Cover and let rise until light and bubbly; overnight in a cool kitchen or 4 – 6 hours in a warm kitchen.
Stir down this sponge and add mashed sweet potatoes, non-dairy milk, salt, ginger, oil, sugar and half of the white whole wheat flour; mix well. Once fully incorporated, gradually stir in enough remaining flour to you create a soft, pliable, dough. Continue kneading for about 15 minutes, only adding more flour as needed to prevent stickiness. Dough should be soft and smooth yet pliable and still slightly tacky. Place dough in an oiled bowl, roll it about to coat, cover and let rise double in a warm place. Allow about 2 hours for it to double in volume.
Preheat your oven to 375 degrees and lightly grease an 8 x 4 inch loaf pan.
Punch down dough and turn it out onto a lightly floured surface. Let rest 10 minutes on the counter before flattening it out . Shape into loaf and place into your prepared loaf pan with the seam side down. Cover and let rise to top of bread pan.
Right before popping the loaf in the oven, use a very sharp knife or blade to slash the dough lengthwise, straight down the center. Bake for 35 – 45 minutes or until golden brown all over. Let cool in pan for 10 minutes before moving the loaf to a cooling rack until it comes to room temperature. Let cool completely before slicing.
