Introduction

r r

When transitioning from using commercial yeast to making sourdough bread, it can be a bit daunting to determine the right amount of sourdough starter to use. However, there is a general rule and some guidelines that can help you make a smooth transition. This article aims to provide a comprehensive guide on how to substitute sourdough starter for yeast in your bread recipes.

Understanding the Substitution

r r

The process of substituting sourdough starter for commercial yeast involves a few steps and considerations. Jane Mason, in her book 'All You Knead is Bread', outlines a straightforward method that many bakers find effective. According to her, the key is to understand that sourdough starter is essentially a culture of wild yeast and lactic acid bacteria. It takes longer to rise than commercial yeast but can produce a more complex and flavorful bread.

General Formula

r r

Another general rule to follow is to use 20% of the total flour weight for your sourdough starter. For example, if you are using 1000 grams of flour, you would add an additional 200 grams of sourdough starter. This figure can adjust slightly depending on the specific recipe, but the 20% ratio is a good starting point.

Additional Tips

r r

For most standard bread recipes, you would generally add between 1.5 to 2 teaspoons of dried yeast. However, when using sourdough starter, you might find that 200 grams of starter can impart sufficient leavening power.

Conclusion

Substituting sourdough starter for commercial yeast is a fantastic way to make your bread more flavorful and unique. By following the steps outlined in this guide, you can successfully transition to using sourdough starter in your bread recipes. Remember, practice makes perfect, and the more you bake, the more comfortable and confident you will become in using sourdough starter.

Detailed Substitution Guide

r r

Step 1: Determine Your Yeast Amount

r r

First, find the amount of fresh yeast that the recipe calls for. For instance, if the recipe requires 7 grams of active dry yeast, double that amount to 14 grams of sourdough starter. Note that 7 grams of active dry yeast is approximately equal to 18 grams of cake fresh yeast.

r r

Step 2: Prepare the Sourdough Starter

r r

Next, use 25 grams of the total flour weight from the recipe and 25 grams of water to create a starter mixture. Mix all the ingredients thoroughly until a smooth dough forms.

r r

Step 3: Let the Starter Rest

r r

Allow the mixture to sit covered for 24 hours. This resting period will help the sourdough starter mature and develop a complex flavor.

r r

Step 4: Adjust Your Recipe

r r

Subtract the amount of flour and water used in the starter from the overall recipe. This adjustment is necessary because the starter also contains both flour and water.

r r

Step 5: Use the Starter

r r

When the 24 hours have passed, you can proceed with the rest of the bread-making process, following your original recipe but using your freshly prepared sourdough starter instead of commercial yeast.

r r

Conclusion

r r

Substituting sourdough starter for commercial yeast is a simple process once you understand the basics. By following these steps, you can create flavorful and unique bread while reducing your reliance on commercial yeast.
