Why This Recipe Works
This recipe is designed for simplicity and reliability. Here’s why it works:
- Equal Parts Flour and Water: The 1:1 ratio of flour to water is easy to remember and provides the ideal environment for yeast and bacteria to thrive.
- Unbleached Flour: Unbleached flour contains more of the natural wild yeast and bacteria that are essential for sourdough fermentation. Bleached flour can hinder the process.
- Consistent Feeding Schedule: Regular feedings provide the starter with a consistent food source, promoting healthy growth and activity.
- Room Temperature: Maintaining a consistent room temperature (around 70-75ยฐF or 21-24ยฐC) is crucial for optimal fermentation.
- Visual Cues: We focus on visual cues like bubbling, rising, and falling to help you understand the starter’s progress and know when it’s ready to bake with.
Ingredients
- Unbleached All-Purpose Flour: 1 cup (120g)
- Filtered Water: 1 cup (240ml), non-chlorinated

Instructions
Day 1: The Beginning
- In a clean, wide-mouth glass jar or container (at least 1 quart in size), combine 1/2 cup (60g) of unbleached all-purpose flour and 1/2 cup (120ml) of filtered water.
- Stir vigorously with a fork or spoon until no dry flour remains and you have a thick, pasty mixture.
- Scrape down the sides of the jar to keep it clean.
- Loosely cover the jar with a lid or plastic wrap. If using plastic wrap, poke a few holes for ventilation.
- Place the jar in a warm place (around 70-75ยฐF or 21-24ยฐC) and let it sit for 24 hours.
Day 2-7: Feeding Time
- Observe: After 24 hours, you might see some small bubbles forming. Don’t worry if you don’t see anything yet โ it’s still early!
- Discard: Discard half of the starter. This is important to prevent the starter from becoming too acidic and to control its growth. You can discard it in the trash or find creative ways to use it (see FAQ).
- Feed: Add 1/2 cup (60g) of unbleached all-purpose flour and 1/2 cup (120ml) of filtered water to the remaining starter in the jar.
- Stir: Stir vigorously until no dry flour remains.
- Cover: Loosely cover the jar and place it back in a warm place for another 24 hours.
- Repeat: Repeat this discard and feed process every 24 hours for the next 5-7 days.
Day 8+: Monitoring Activity and Adjusting Feedings
- Observe: By day 8, you should start seeing more significant activity โ a noticeable rise in the starter after feeding, followed by a gradual fall. You’ll also notice more bubbles throughout the mixture. The starter should have a pleasant, slightly tangy aroma.
- Change to 12-hour Feedings (Optional): If your starter is very active (doubling in size within 4-6 hours after feeding), you can switch to feeding it every 12 hours. This will provide it with a more consistent food supply and keep it at its peak.
- Float Test: To test if your starter is ready to bake with, perform the float test. Take a small spoonful of starter and gently drop it into a glass of water. If it floats, it’s ready! If it sinks, continue feeding it every 12 or 24 hours until it passes the float test.
Tips for Success
- Use a Kitchen Scale: For consistent results, using a kitchen scale to measure your flour and water is highly recommended.
- Warmth is Key: A warm environment is essential for fermentation. If your kitchen is cold, try placing the starter in a slightly warmer spot, such as near the oven (but not on top!) or inside a turned-off oven with the light on.
- Be Patient: Sourdough starter development takes time. Don’t get discouraged if you don’t see immediate results. Just keep feeding it consistently, and it will eventually come to life.
- Observe and Adjust: Pay attention to your starter’s activity and adjust the feeding schedule as needed. If it’s doubling quickly, feed it more frequently. If it’s sluggish, try moving it to a warmer spot.
- Use Good Quality Water: Avoid using tap water that contains chlorine or chloramine, as these can inhibit the growth of yeast and bacteria. Filtered water is best.
- Cleanliness Matters: Always use clean utensils and jars to prevent contamination.
- Don’t Give Up! Sometimes, a starter can take longer to develop than others. Persistence is key!
Storage Instructions
For Regular Baking:
- Keep your starter at room temperature and feed it regularly (every 12-24 hours) if you plan to bake frequently (several times a week).
For Infrequent Baking:
- Store your starter in the refrigerator. This will slow down its activity and reduce the need for frequent feedings.
- Feed the starter once a week, even when refrigerated.
- Before baking, take the starter out of the refrigerator and feed it for 1-2 days to revive it and increase its activity.

FAQ
What do I do with the discard?
Don’t throw it away! Sourdough discard can be used in a variety of recipes, such as:
- Sourdough pancakes or waffles
- Sourdough crackers
- Sourdough pizza dough
- Sourdough biscuits
- Sourdough discard bread
My starter smells bad. Is that normal?
In the early stages, it’s common for the starter to have a slightly unpleasant odor, such as a cheesy or vinegar-like smell. This is usually due to the presence of different types of bacteria. As the starter matures and the beneficial yeast and bacteria take over, the smell should become more pleasant and tangy.
My starter isn’t bubbling. What should I do?
Make sure your starter is in a warm place and that you’re using unbleached flour and filtered water. Be patient and continue feeding it regularly. It may take a few days or even a week for the bubbling to start.
Can I use a different type of flour?
While unbleached all-purpose flour is the easiest to use for beginners, you can experiment with other types of flour, such as whole wheat flour or rye flour. These flours contain more nutrients and can add unique flavors to your starter. However, they may also require adjustments to the feeding schedule.
How do I know if my starter is ready to bake with?
The best way to tell if your starter is ready to bake with is to perform the float test. It should also have doubled in size within 4-6 hours after feeding and have a pleasant, tangy aroma.
