Fresh milled sourdough sandwich bread

The holy grail of bread baking? Fresh flour sourdough.

For years after I made the switch to fresh milled flour, I assumed I just wasn’t going to make good sourdough bread again. I was cranking out beautiful commercial yeast loaves. But whenever I attempted sourdough bread with fresh flour, I was very discouraged with the results.

So I perfected my Fresh Flour Sandwich Bread, made with yeast. And it’s still a favorite in our house.

Then I decided to conquer fresh milled sourdough bread. It took me some time, but I was determined.

And, friends, I’m here to tell you that fresh milled sourdough bread truly is the most delicious and nutritious bread in the world. (Keep reading, I’ll convince you too.)

Soft & sturdy sourdough bread. With fresh flour.

This recipe was my breakthrough.

It’s soft enough to make brioche-style French toast.

It’s sturdy enough to hold up to a juicy heirloom-tomato BLT sandwich.

It’s great for toast (with butter or avocado), grilled cheese (my husband actually insists that grilled cheese made with this sourdough bread is the best ever), egg & cheese souffle, and the list goes on. Anything your “regular” sandwich bread can do, this loaf can do better.

Fresh milled flour gives this loaf deep, earthy flavor, combined with the classic “tang” of sourdough.

What is fresh milled flour?

Flour comes from whole grain wheat kernels. These kernels are grown, harvested, and ground into flour. On their own, whole wheat kernels are incredibly nutritious. They’re packed full of all kinds of essential vitamins and minerals, fiber, and protein.

The problem? Commercial flour at the grocery store has been processed and stripped of essentially all the nutrients that the whole wheat berries once contained.

Why? Wheat berries contains oils. These oils are incredibly nutritious, but they pose a problem for commercial millers. Oil goes rancid once the wheat berries are milled. But when the bran & germ (the source of the oils) is removed from commercial flour, it lasts almost indefinitely. When Big Food can create food with a long shelf life, profits soar.

Add in to the commercial flour many dough enhancers, bleaching agents, added enzymes, and synthetic vitamins, not to mention the pesticides in traditional flour, and you have a recipe for indigestibility, gluten intolerance, and poor gut health (source). Crazy that we’ve villanized gluten for decades, when the gluten was never really the problem.

The case for grain mills + wheat berries

On the flip side of commercial flour that’s been sifted, heated, bleached, and a million additives added? Nutrient-dense fresh milled flour.

Purchasing a grain mill + wheat berries allows you to mill fresh, whole grain flour, on demand.

Your body loves fresh milled flour, thanks to its high fiber and protein content, along with the natural oils present in fresh flour. You’re able to mill your flour on-demand, and turn around and turn that flour into the most nutritious bread in the world.

No bleaching agents.

No added enzymes, dough enhancers, or additives.

No synthetic vitamins.

And no pesticides if you’re sourcing good grains.

Fresh milled flour is real, whole grain flour, naturally packed with vitamins. Naturally containing everything you need to make great bread.

Why use fresh milled flour in sourdough?

Sourdough bread that’s long fermented is easier for our bodies to digest.

Sourdough made with commercial flour (read more about that above), is not only missing nutrients but is also filled with synthetic additives. Long-fermented (sourdough) bread made with commercial flour is, unfortunately, not the epitome of nutritiousness. (Don’t get me wrong, though, any homemade bread will still be 100% better for you than prepackaged options.)

Sourdough AND fresh milled flour?

Fresh flour sourdough is a powerhouse combination of easy-to-digest (long-fermented) REAL vitamins and minerals (not synthetic ones) and all the natural nutrients housed in the wheat berry as it was grown in the farmer’s field, with nothing missing. 

Fresh milled sourdough bread truly is the most nutritious bread in the world.

What wheat berries to use in sourdough sandwich bread

You’ll notice that this recipe simply calls for “hard red wheat.” That’s a generic term that can include several different kinds of wheat–but usually the term refers to modern varieties.

If you’re new to fresh milled flour, and you have “hard red” in your kitchen, just stick with that and use it up.

If you’re looking to maximize nutrients, I love ancient and heritage grains. Turns out, specific varieties of hard red wheat have been preserved throughout generations–and have avoided commercial hybridization. These heritage (and older ancient) grains are always more nutritious and flavorful. (source and source)

My favorite varieties of heritage hard red wheats include Turkey Red and Rouge De Bordeaux. Or you can stick with “classic” hard red wheat, like this one.

This recipe also works well with spelt, khorasan, or any combination of these grains. It’s nice to switch up your combination occationally for a varied nutrient profile and a slightly different taste.

What’s the secret to soft sourdough with fresh flour?

I finally found the secret to soft sourdough sandwich bread with fresh milled flour. Turns out, the combination of making a preferment and also adding a tangzhong to the dough = magic.

It might sound complicated, but it’s not.

The preferment just means you take a little time to let your flour soak in the liquid. This step ensures that you’re working with active, well-fed starter in the right amount and right thickness. It creates consistency.

A tangzhong is a simple process of cooking some of the liquid and flour before adding it to your recipe. This helps the dough hold moisture and leaves your dough softer, sturdier, and helps it stay fresh longer.

The secret to soft sourdough sandwich bread with fresh milled flour?

A preferment + a tangzhong.

We’ll chat about these methods more below. Stick with me.

Can I add a tangzhong to sourdough with fresh flour?

There’s a common misconception that enhancements shouldn’t be added to sourdough bread.

Not true.

I’ve seen great improvement in the texture, flavor, and length of freshness in my sourdough when I add a tangzhong to my dough.

So yes, you absolutely can add a tangzhong to your sourdough sandwich bread, and, in fact, I reccomend it. It makes a world of difference.

Why isn’t my fresh flour sourdough rising?

If you’re struggling to get your sourdough to rise well when it’s made with fresh milled flour, let me share a few tips I’ve learned over the years.

  • Don’t be afraid to knead your sourdough. Especially sandwich bread doughs really benefit from a good kneading (and I’m not just talking stretch and folds, although they have their place). In this recipe, I treat the dough very similarly to how I treat my yeasted sandwich bread dough.
  • Make sure your sourdough starter is super strong, active, and well-fed. When you’re baking with fresh milled flour, it’s essential to use the strongest starter possible.
  • Add a tangzhong to your dough. (See above for more about tangzhong and why it helps.) This will help your bread not only develop strength, but also develop into a softer, sturdier, and longer lasting loaf.
  • Use the right wheat berries. If you’re struggling to make sourdough bread with fresh flour, try switching up not only just the type of grain you’re using, but also where you’re sourcing your grains from. High-quality grains, dried properly, and sourced carefully will improve your bread. See all my favorite choices here.

Keyword: bread, sourdough bread, sandwich bread
Servings: 1 large loaf

Equipment

  • grain mill
  • loaf pan
  • high-powered mixer optional

Ingredients

preferment

  • ¾ cup 200 g active sourdough starter
  • ½ cup warm water
  • 1 cup 130 g hard red flour*

tangzhong

  • 6 tablespoons milk
  • 2 tablespoons 16 g hard red flour*

For the dough

  • all of the preferment
  • all of the tangzhong
  • cup milk
  • 1 large egg
  • 1 tablespoon honey
  • 1 teaspoon salt
  • 3 cups 390 g hard red flour*

to add after the dough is in the mixer:

  • 1/4 cup butter softened

Instructions

  • The night before, mix all the ingredients of the preferment together. a shaggy dough. Cover and let rest at room temperature overnight.
  • The next morning, make the tangzhong by whisking the milk and flour over high heat constantly until it thickens into a paste. Add the tangzhong to your preferment from the night before, along with the milk, egg, honey and salt. Mix and slowly add about 1 ½-2 cups of the flour, or more if needed, until a soft, sticky dough forms. Don’t add all the flour at once, it’s better to add more at the next stage, when it gets kneaded, than to add too much now. And you may find you don’t need to add any more flour at all. Cover the bowl again and allow it to sit for at least 10 minutes. (I usually let it sit about ½ hour, and even longer is fine.)
  • After the dough has rested, add the dough to your mixer’s bowl and start kneading the dough. If the dough seems extra sticky, add more flour as your mixer is kneading it. You want your dough to be soft but not too sticky. After kneading for about 5 minutes, the dough should start to look stretchy and supple. As the mixer continues to knead, cut your softened butter into slices and slowly add it into the mixer. At first, your dough may be a buttery mess, but after another 10 minutes or so of kneading with the butter incorporated, it should come together to form a soft, stretchy dough that’s slightly sticky but easy to work with.
  • If your dough is still overly sticky at this point, add a little more flour, slowly, as the mixer is kneading, but no more than ¼ cup at a time. After a few more minutes of kneading if it’s still too sticky, add another ¼ cup and keep doing that (but don’t exceed 3 cups by too much, total unless your dough truly needs it), until you have a soft, stretchy, sticky (but manageable) dough. Be patient and give your dough plenty of kneading time. I’ve been known to let this dough knead for ½ hour in my mixer, or even more.
  • Grease a large bowl, roll your dough in the oil to cover all sides, and let the dough rise in the bowl until it has almost doubled (could be as long as 3 hours, depending on how warm or cool your home is on baking day). After the dough has almost doubled, gently scrape it onto a work surface to shape your loaf.
  • Rub or spray some oil on the top of your loaf (to keep it from drying out as it finishes rising), cover your pan, and set aside to rise again for about 3 more hours. When your dough has risen well, uncover your pan and score the dough.
  • Bake at 350 for about 35-40 minutes, or until an instant read thermometer inserted into the center of your loaf reads 190-200 degrees. Let the loaf cool slightly in the pan, then gently dump it out onto a cooling rack. Brush the top of the loaf with butter while it’s still warm, to keep the crust soft, let your bread rest for about 20 minutes, and enjoy!

Notes

*I prefer to use a nutritious heritage Hard Red wheat, like Turkey Red or Rouge De Bordeoux.
