How To Make Sourdough

Sourdough bread is one of the oldest forms of bread known. It’s so old that it is impossible to tell just how old it is! The oldest loaf found dates back to 3700 B.C. and was excavated in Switzerland. Now that is an old loaf of bread.

But what makes sourdough bread so different from others is that it’s the only bread that requires fermentation before baking. Sourdough resists mold naturally due to the bacteria that converts the linoleic acid in bread flour to a compound that has powerful antifungal activity.

But that’s not all! This bread helps to maintain glucose levels in the body making it ideal for diabetics. It also contains a lot of goodness in terms of nutrients: B1 through 6, folate, thiamin, and niacin, just to name a few.

These are all wonderful reasons to eat this bread, but the reason I eat it is for the distinct tangy flavor!

Did you know that there are wild yeasts that are floating around in the air? This is how our ancestors made leavened bread prior to the development of commercial yeast.

Wild yeast can be harnessed to leaven your bread by leaving uncooked dough exposed to the air for a bit before baking. Airborne yeasts will settle into the mixture and eat the natural sugars in the bread. This is what gives the sourdough bread its signature tangy flavor.

Every sourdough recipe begins with a great starter. What is a starter you ask? Read on to find out and how you can make your own!

Sourdough Starter Recipe

Before you can make a beautiful sourdough bread you need to make a sourdough starter. You can use milk or water to start as well as wild yeast or commercial yeast. Commercial yeast is more predictable, but wild yeast will work as well.

Tools Needed


  • 1 cup water
  • 1 cup flour
  • 1 tablespoon commercial yeast or wild yeast


  1. Blend all of the ingredients together in a wide-mouthed jar and cover with cheesecloth.
  2. Secure the jar with a rubber band so that nothing contaminates the starter. Do not add a tight-fitting lid to your container as this mixture is fermenting and it could cause the container to erupt.
  3. Place your starter in a warm spot to encourage the yeast to grow. Near a stove or on top of the fridge are great places, but anywhere that is warm will work.
  4. The natural yeast found in the flour and in the air or the commercial yeast will start bubbling anywhere from 2-5 days depending on the warmth of your kitchen.

  5. Every 12 hours throughout the 2-5 days, add equal amounts of flour and water.
  6. If you see a liquid layer on top of your starter, don’t worry, this liquid is known as hooch and indicates that your starter needs to be fed, so go ahead and pour off the liquid and add equal amounts of flour and water.

Any extra sourdough starter can be put into the fridge until you are ready to use it. Just take it out the night before, replenish it with equal amounts of flour and water, and let it sit overnight. Then, pour off the amount needed for the recipe and put back into the fridge with a lid.

Once you have enough starter and it is nice and bubbly it is time to get baking!

You can make all sorts of things with your sourdough starter. Pancakes, waffles, biscuits, cakes, muffins and of course, bread.

This is my favorite French bread recipe adapted from a World Of Breads by Dolores Casella. It’s simple to make and quite delicious.

  6. Stir in the next 2 cups of flour and the salt. This should be enough for a firm dough.
  7. Turn dough out onto a floured surface and knead thoroughly.
  8. Place in a well-buttered bowl and let rise until the dough has doubled in size.
  9. Punch dough down and let it rise again for 30 minutes.
  10. Turn dough out onto floured surface, and let it rest for 10 minutes.

  12. Place onto pizza stone or a well-greased baking sheet with cornmeal sprinkled on it.
  13. Let the loaf rise again until size has doubled.
  14. Place in preheated oven at 400 degrees Fahrenheit for 50 minutes.
  15. You can slash the bread with a very sharp knife or razor just prior to putting into the oven if desired. If the utensil is very sharp the bread will not fall.

  16. For a shiny crust, blend an egg white with a tablespoon of water and brush several times during baking.

Sourdough bread is nutritious and contains higher levels of folate and antioxidants than other bread. It is lower in phytate; this allows your body to absorb the nutrients more easily.

It also contains lower amounts of gluten, and because it is fermented, it contains probiotic and prebiotic properties that make this bread not only easier to digest, but studies have shown that it may better control blood sugar levels and improve insulin sensitivity.
