A detailed guide on how to revive dried sourdough starter to full strength in less than a week.
Ingredients
- 5 grams dried sourdough starter
- 120 grams unbleached bread flour, divided
- 125 grams filtered water room temperature
Instructions
- Day One Morning: Combine 5 grams finely crumbled dried sourdough starter in a small glass jar. Add 25 grams (100°F/38°C) filtered water. Stir until the dry starter is completely submerged. Cover and allow to sit for one hour at 76°F/24°C or room temperature.
- After an hour, add 20 grams bread flour and stir until thoroughly combined. Note: We're using slightly more water than flour in this first feeding — a thinner starter allows for increased yeast and bacteria activity. Cover and store at room temperature for 24 hours.
- Day Two Morning: Combine 10 grams starter (discard the rest), 25 grams bread flour, and 25 grams room temperature filtered water. Mix until combined. Cover and store at room temperature for 24 hours.
- Day Three Morning: Repeat Day Two — 10 grams starter, 25 grams flour, 25 grams water. Cover and store at room temperature for 24 hours.
- Day Four Morning: Combine 10 grams starter, 25 grams flour, 25 grams water. Cover and store at room temperature — check back in about 12 hours.
- Day Four Evening: Roughly 12 hours later, you'll notice many small bubbles on the surface and sides, and the starter should show signs of slowly rising. Continue storing at room temperature.
- Day Five Morning: The mixture should have nearly doubled in volume with small and big bubbles throughout. Allow starter to reach peak activity before proceeding. If everything is on track, you can get back to baking!
- Once at peak activity, start regular daily feedings: 5–10 grams starter, 25 grams flour, 25 grams water. Store at room temperature until starter reaches peak activity. Repeat.
