Sourdough Starter Recipe (VIDEO)

The Sourdough Starter Recipe details cultivating a natural leavening mixture using whole grain rye or whole wheat flour, all-purpose flour, and filtered water. Over several days, the starter develops bubbles and rises as wild yeast and bacteria ferment the mixture. This starter is a foundation for baking sourdough bread, relying on consistent feeding and proper temperature to create an active, healthy culture.

Description

This sourdough starter recipe begins by combining whole grain rye or whole wheat flour with water, stirred and rested at room temperature for 24 hours. Subsequent days involve discarding a portion of the starter and feeding it with all-purpose flour and water to encourage yeast growth. Ideal temperature for fermentation is 68-75°F, as cooler environments may slow development.

Over time, bubbles form, and the starter expands, signaling active fermentation. Using filtered or dechlorinated water is essential because chlorine can inhibit yeast and bacterial activity. Patience and consistent feeding schedules play a critical role in developing a strong starter suitable for sourdough baking, enabling bread to rise naturally without commercial yeast.

The recipe includes tips on monitoring growth, maintaining consistent feeding, and emphasizes the variability in starter development speed depending on environment. Proper care results in a reliable, lively starter to incorporate in artisan bread recipes.

Ingredients

Servings
  • 100 g whole grain rye flour preferably organic (100g = 3/4 cup, or whole wheat flour
  • 500 g all-purpose flour used to maintain and feed the starter, preferably organic and avoiding bleached flour
  • 1 qt filtered water room temperature, or spring water

Instructions

Day 1 Make your Starter

  1. Record the weight of your jar in grams before you add anything and label the jar with your starting date for easier tracking.
  2. Add 100 grams (3/4 cup) whole wheat or rye flour and 100 grams (1/2 cup) water. Stir together thoroughly with a fork (it will be very thick), scrape down the sides with a spatula. Cover with a loose-fitting lid and let it rest at room temperature for 24 hours*. Put a rubber band around your jar to mark the growth of your starter. Label the jar with a date to track.

Day 2: No Changes Noted

  1. Likely nothing is happening. You might see some tiny bubbles or it will look exactly the same. Let it rest for another 24 hours

Day 3 (stage 2) Visible Growth and Bubbles in Jar

  1. Remove and discard half of the starter in the trash so it does not affect the plumbing. You should have 100 grams (1/2 cup) of starter left. Add 100 grams (3/4 cup) all-purpose flour and 100 grams (1/2 cup) room temp water. Stir thoroughly, scrape down the sides of the jar, cover loosely, and rest at room temperature for 24 hours

Day 4 (72 Hours into the process): See a lot of bubbles

  1. Remove and discard all but 100 grams of starter. Add 100 grams (3/4 cup) all-purpose flour and 100 grams (1/2 cup) room-temperature water. Stir thoroughly, scrape down the sides of the jar, cover loosely, and rest 24 hours. Note: In a couple of my many tests, my starter seemed to slow down its growth on day 4 for no apparent reason. If that happens, just keep feeding it - it will turn back around.

Day 5: Visible growth and bubbles.

  1. Remove and discard all but 100 grams of starter. Add 100 grams (3/4 cup) All-purpose flour and 100 grams (1/2 cup) room-temperature water. Stir thoroughly, scrape down the sides of the jar, cover loosely, and rest 24 hours.

Day 6-7: Your starter may double or more

  1. Remove and discard all but 100 grams of starter. Add 100 grams (3/4 cup) All-purpose flour and 100 grams (1/2 cup) room-temperature water. Stir thoroughly, scrape down the sides of the jar, cover loosely, and rest until more than doubled in volume.

Testing Your Starter

  1. When your starter is ready, it should peak between 4-6 hours and start to recede after 12 hours. It should smell sour and pleasant, drop a dollop of your starter into a bowl of water. If it floats, it’s healthy enough to use in recipes. If your starter isn’t ready by day 7, continue feeding it following this schedule. It may take a bit longer depending on many factors—such as the flour use and the environment.

How to Maintain your starter

  1. For frequent bakers: store at room temperature. Discard and feed every 24 hours. To use the starter, feed and wait for the starter to reach its peak, 4-6 hours then remove the portion needed for the recipe.
  2. For casual bakers (weekly): store in the fridge. Once a week, discard and feed the starter, then let it rest at room temperature for 1 to 2 hours before returning it to the fridge. If baking, remove the starter from the fridge and bring to room temperature overnight. Discard and feed. When the starter reaches its peak, remove the portion needed for the recipe, then feed and refrigerate.

Notes

  • Maintain the starter at a consistent room temperature between 68-75°F for optimal fermentation speed.
  • Use filtered or dechlorinated water to avoid inhibiting yeast and bacterial growth.
  • Feed the starter at the same time each day for consistent development.
  • Starters vary in development time; patience is essential to avoid rushing the process.
  • In colder kitchens, find a warmer spot or use lukewarm water to help yeast activity.
