Ingredients
Sourdough Starter
- 500 grams (about 4 1/2 cups) rye flour
- 500 grams (about 4 1/2 cups) warm water
Levain
- 85 grams (about 3/4 cup) mature sourdough starter
- 150 grams (about 1 cup) bread flour
- 50 grams (about 1/3 cup) whole wheat flour
- 175 grams (about 3/4 cup) warm water
Directions
- For the sourdough starter -- Day One: Use a fork to mix 100 grams (1/2 cup) of rye flour and 100 grams (1/2 cup) of warm water in a glass mason jar or any type of container that has a lid. Cover and leave at room temperature for 24 hours.
- Day Two: You will probably see some sort of activity depending on how warm your kitchen is. The smell may not be so pleasant. Reserve 100 grams (about 1/2 cup) of the mixture and discard the rest. Feed another 100 grams (1/2 cup) of rye flour and 100 grams (1/2 cup) of warm water to the original mixture and leave at room temperature for another 24 hours.
- Day Three: You may see the markings on the walls of the jar from a "rise and fall" of the new starter, along with nice bubbles and air pockets. This is good. The smell should be getting a bit more bearable. Repeat the process of Day Two.
- Day Four: There will definitely be a good volume increase and a consistent amount of bubbling and air pockets. There should be a somewhat sweet and sour smell that is pleasant. You're in the home stretch. Repeat Day Two one more time.
- Day Five: By this point, you should have a ripe and sweet-smelling sourdough starter. You should see some movement of the bubbles when you jostle the container and a structure when you stir it. You are now ready to build a levain.
- For the levain: Use a fork to mix the mature starter, bread flour, whole wheat flour, and warm water in a container, then let it rest at room temperature until the mixture is covered in bubbles and air pockets for 3 to 4 hours.
