Potato Flake Sourdough Bread with Freshly Milled Flour

Magen Jones - littletennesseehome.com
Potato flake sourdough bread with freshly milled flour is seriously taking your sourdough game to the next level. I didn't think there could be anything better than potato flake sourdough bread made from scratch, until I learned that you can mill your own flour at home!
Prep Time 40 minutes
Cook Time 35 minutes
Fermentation 16 hours
Total Time 17 hours 15 minutes
Course Side Dish
Servings 2 9x5 loaves

Equipment

  • Grain Mill
  • Stand mixer with dough hook attachment or large bowl and wooden spoon
  • measuring cups and spoons
  • Dough scraper
  • Plastic Wrap or Beeswax Wrap
  • 2 loaf pans (9x5)
  • Kitchen scale

Ingredients
  

  • 6 cups freshly milled flour (2½ cups hard white wheat, 2½ cups hard red wheat, 1 cup soft white wheat) 845 grams total
  • 1 cup active potato flake sourdough starter 252g
  • ½ cup mild olive oil 96g
  • 4 tablespoons vital wheat gluten 37g
  • ½ cup raw organic sugar 98g
  • 2 cups warm water 437g
  • 1 tablespoon salt

Instructions
 

Mix the Dough

  • ​Start by giving your potato flake starter a quick stir, then measure out 1 cup. Add it to the bowl of a stand mixer along with the 2 cups of warm water, oil, sugar, vital wheat gluten, and all of the freshly milled flour (but leave out the salt for now).
  • Mix everything together until there’s no dry flour left. You don’t need to knead at this point—just get everything incorporated.
  • Cover your bowl with plastic wrap or beeswax wrap and let the bread dough rest for 30 minutes. This rest time is called the autolyse, and it gives your flour time to hydrate and begin forming gluten naturally.

Add Salt and Knead

  • ​After the dough rest, sprinkle in the tablespoon of salt. Knead the dough using the dough hook attachment on low to medium speed for about 5 minutes. The dough should come together into a soft, stretchy dough ball. It’ll be tacky but shouldn’t stick much to your hands.

Bulk Fermentation

  • Remove the dough with oiled hands and form it into a ball. Lightly oil your bowl, return the dough to the bowl, and cover again. Let it rise in a warm place until doubled in size, anywhere from 5 to 10 hours depending on the temperature of your kitchen and the strength of your active starter. This is known as the bulk fermentation or first rise.

Shape the Loaves

  • Once the dough has doubled, use your dough scraper to gently loosen it from the sides of the bowl and turn it out onto a clean surface.
  • Try to avoid adding too much extra flour unless it’s really sticky—any added flour at this point won’t have the benefit of fermentation and can change the final texture.
  • Divide the dough into 2 equal parts (mine weighed about 911g each). You can also make smaller loaves if you prefer.

Now it’s time to shape:

  • Use the guide below to help with shaping:
  • Gently press each piece into a rough rectangle.
  • Fold the top third of the dough down toward the center, pressing lightly.
  • Fold each side in toward the center, one at a time.
  • Roll the dough up from the top edge down toward you, pressing gently as you go to seal each layer.
  • Flip it seam-side down. Use the sides of your hands to rock or slightly pull the loaf toward you, creating surface tension and tightening the shape.
  • This technique helps create a strong outer structure so the loaf holds its shape during the final rise and bake. It also gets rid of any large air pockets and encourages even crumb throughout.
  • Avoid tearing the top of the dough—you want tension, not rips. If it starts to tear, rest it for a few minutes to relax the gluten.
  • Use a bench scraper if the dough is sticking to the work surface. It can help you shape without having to add extra flour.

Final Rise

  • Place each loaf into a greased or parchment-lined bread pan and cover lightly. Let it rise until it has domed at the top and nearly doubled again. You don’t want it to over-proof—if it rises too much, you’ll get big air pockets just under the crust.

Bake

  • After fermentation, preheat your oven to 350°F. Once the loaves are ready, remove the wrap and place them on the oven rack.
  • Bake for 35 minutes, covering loosely with foil for the last 10 minutes if the tops are browning too quickly.
  • If you’re using lidded pans bake for a full 40 minutes. Either method will give you great results.
  • The internal temperature should read 190–200°F when fully baked.

Cool Before Slicing

  • This part is so hard, but let your homemade bread cool completely before slicing. Cutting too soon can lead to a gummy or doughy texture inside—trust me, it’s worth the wait!

Notes

Vital Wheat Gluten: Don’t skip this! It helps add structure to the bread, especially when using 100% whole wheat sourdough or whole grain flour.
Use oiled hands when shaping the dough—it makes everything easier and prevents sticking.
Avoid over-proofing the second rise. If it goes too far, the top crust can separate or collapse after baking.
Want a softer crust? You can brush the tops with butter while the bread is still warm.
Storage: Store your bread in an airtight container or bread bag at room temperature for up to 3 days, or freeze for longer storage.
Cooling: Allow the bread to cool for about 10-15 minutes in the pan, then transfer to a wire rack to finish cooling. This keeps the bread from getting too sweaty in the pan but allows it to finish cooking a few more minutes. 
Don't skip the autolyse step: This step is crucial because FMF (freshly milled flour) takes longer to hydrate and soaks up more water than flour from the store.
