What is Sourdough Starter?
Before we dive into the recipe, it’s essential to understand the science behind sourdough fermentation. Sourdough starter is a natural leavening agent that dates back centuries and is responsible for giving sourdough bread its unique flavor, texture, and rise.
Sourdough starter is a symbiotic culture of yeast and lactic acid bacteria that work together to produce carbon dioxide gas, which makes the bread rise. The key ingredients for a sourdough starter are flour and water, and the balance between these two is crucial for its success. The fermentation process produces lactic acid, giving the bread its characteristic tangy flavor.

Day-by-Day Easy Sourdough Starter Recipe
Once you have all the ingredients ready, follow this day-by-day guide below to create your own homemade sourdough starter:

Day 1: Initial Starter Mix
The first day is the foundation of your sourdough starter. Follow these steps:
- In your glass or ceramic container, combine 100 grams of flour with 100 grams of water. Mix thoroughly until you achieve a smooth consistency.
- Loosely cover the container with its lid or a cloth. Avoid using an airtight seal, as wild yeast requires oxygen to thrive.
- Store the container at room temperature (around 70°F or 21°C) away from direct sunlight and drafts.
Day 2: First Feeding
Congratulations on completing day one! Now, let’s feed your starter:
- You may notice tiny bubbles on the surface, indicating that fermentation has begun. This is a positive sign that wild yeast is colonizing the mixture.
- Discard half of the starter (approximately 100 grams) to reduce the volume.
- Add 100 grams of fresh flour and 100 grams of water to the remaining starter. Mix well.
- Cover loosely and return to the same spot.
Day 3 to 5: Regular Feedings
For the next few days, maintain a consistent feeding schedule:
- Your starter should be showing more bubbles and possibly an increase in volume. This indicates that fermentation is becoming active.
- Continue the process of discarding half of the starter and feeding it with equal parts of flour and water (100 grams each).
- You may notice changes in the aroma, with a mildly sour or tangy smell developing.
Day 6: The Mature Starter
By day six, your sourdough starter should be vigorous and ready to bake with:
- The starter should have doubled in volume within 4–6 hours after feeding.
- It should have a pleasant and pronounced sour aroma.
- The texture should be bubbly and elastic.

Maintaining and Storing Sourdough Starter
Maintaining your sourdough starter is simple. You can keep it at room temperature and feed it regularly to keep it active. Alternatively, you can refrigerate it and feed it once a week. To rejuvenate an inactive starter, take it out of the fridge, feed it for a few days, and it will regain its vitality.
Troubleshooting Your Sourdough Starter
If you encounter any issues with your sourdough starter, here are some common troubleshooting tips:
- Slow Fermentation: Ensure your starter is at the right temperature (around 70°F) and use warm water when feeding.
- Foul Odor: A strong, unpleasant smell may indicate contamination. Start over with fresh flour and water.
- Mold: If mold develops on the surface, discard the starter and sterilize your container before starting again.
Conclusion
Congratulations! You have successfully created a robust and active sourdough starter. With patience and dedication, you can now enjoy endless baking adventures and create delicious artisanal bread right in your kitchen. Remember, a well-maintained sourdough starter becomes better with time, so keep experimenting and perfecting your baking skills.
