Ingredients

Day 1

• 100g bread flour
• 60g filtered water, room temperature
• 20g active sourdough starter (or create one from scratch using flour and water)

Daily Feedings (Days 2–7)

• 50g mature stiff starter
• 100g bread flour
• 60g filtered water

Hydration: 60%

Equipment

• Glass jar or food-safe container
• Digital kitchen scale
• Dough scraper
• Silicone spatula or wooden spoon
• Loose-fitting lid
• Rubber band or marker to track growth

Instructions

Day 1 – Mix the Starter

1. In a clean bowl, combine:
   • 20g active sourdough starter
   • 60g filtered water
2. Stir until the starter is mostly dissolved.
3. Add 100g bread flour.
4. Mix until a firm dough forms.
5. Knead for 1–2 minutes until smooth.
6. Shape into a ball and place it in a clean glass jar.
7. Mark the starting level with a rubber band.
8. Cover loosely and leave at room temperature (72–78°F / 22–26°C) for 24 hours.

The dough should feel soft but firm, similar to bread dough.

Day 2 – First Feeding

1. Remove and discard all but 50g of the starter.
2. Add:
   • 100g bread flour
   • 60g filtered water
3. Mix into a firm dough.
4. Knead briefly until smooth.
5. Return to the jar.
6. Cover loosely and ferment for another 24 hours.

You may notice a few bubbles and a mild yeasty aroma.

Day 3 – Build Strength

Repeat the feeding:

• Keep 50g starter.
• Add 100g bread flour.
• Add 60g water.
• Knead until smooth.

Allow to ferment for another 24 hours.

The starter should begin showing small air pockets inside when cut open.

Day 4 – Increased Activity

Feed again using the same ratio:

• 50g starter
• 100g bread flour
• 60g water

Shape into a smooth ball and place back into the container.

The starter may begin rising noticeably between feedings.

Days 5–7 – Mature Starter

Continue feeding every 24 hours until the starter:

• Doubles in size within 4–8 hours
• Feels light and airy inside
• Has a pleasant, mildly tangy aroma
• Holds its shape while still expanding well

Once these signs appear consistently, your stiff starter is ready to use in recipes.

Daily Maintenance

If kept at room temperature:

Feed every 24 hours using:

• 50g starter
• 100g bread flour
• 60g filtered water

Knead into a smooth dough each time.

Refrigerator Storage

For occasional baking:

1. Feed the starter.
2. Let it sit at room temperature for 1–2 hours.
3. Refrigerate in a loosely covered container.

Feed once every 5–7 days.

Before baking:

• Remove from the refrigerator.
• Feed once or twice at room temperature.
• Wait until the starter doubles before using.

Signs of a Healthy Stiff Starter

Your starter is ready when it:

• Doubles in volume after feeding
• Has small, evenly distributed air pockets
• Smells mildly sweet, yeasty, and slightly tangy
• Feels elastic when stretched
• Maintains a rounded shape while expanding

Troubleshooting

Starter Isn’t Rising

• Move it to a warmer location (75–78°F / 24–26°C).
• Use filtered water if your tap water contains chlorine.
• Feed consistently every 24 hours.
• Mix in a small amount of whole wheat or rye flour for a few feedings to encourage activity.

Dry Surface

If the surface becomes dry, cover the container more securely while still allowing a small amount of airflow.

Sour Smell

A mild tangy aroma is normal. If the starter develops pink, orange, green, black, or fuzzy mold, discard it immediately and start with a clean container.

Pro Tips

• Bread flour provides the strongest gluten structure.
• Always weigh your ingredients for consistent hydration.
• Kneading the starter briefly helps strengthen the gluten network.
• Mark the container after every feeding to monitor growth.
• Keep the starter in a warm, draft-free environment for the best fermentation.

Best Uses for a Stiff Sourdough Starter

• Artisan sourdough bread
• Panettone
• Brioche
• Croissants
• Cinnamon rolls
• Bagels

A Stiff Sourdough Starter is an excellent choice for bakers who want a strong, reliable culture with slower fermentation and a milder flavor profile. Its firm consistency promotes excellent dough strength and is ideal for both artisan breads and enriched pastries, making it a versatile addition to any home bakery.
