Ingredients

Scale

  • 100g whole wheat flour (for Day 1)

  • 300g unbleached all-purpose flour (for Days 2–7)

  • 400ml filtered water (room temperature)

Instructions

Day 1:

  1. In the glass jar, mix 50g whole wheat flour with 50g filtered water.

  2. Stir until smooth. Cover loosely with cloth. Let it rest in a warm place (68–75°F / 20–24°C).

Day 2–7:

  1. Discard half of the mixture (around 50g).

  2. Feed with 50g all-purpose flour and 50g filtered water.

  3. Stir, cover, and rest. Repeat daily at the same time.

By Day 5–7:

  • Your starter should be bubbly, tangy-smelling, and double in volume 4–6 hours after feeding.

  • Test readiness with the “float test” (drop a spoonful into water—it should float).

Notes

  • Use your starter once it’s consistently rising and passing the float test.

  • Refrigerate and feed once weekly if not baking daily.

  • Discard can be used in sourdough burger buns or pancakes!
