Description

Sourdough starter magic begins with simple flour and water, creating a living culture of wild yeast and bacteria. This homemade fermentation process connects you to generations of bakers, offering a gateway to delicious, tangy bread that fills kitchens with warmth and flavor.


Ingredients

Scale

Main Ingredients:

  • 1 cup (120 grams) whole wheat flour
  • 1 cup (120 grams) all-purpose flour (unbleached preferred)

Water Ingredients:

  • ½ cup (120 milliliters) filtered water
  • ½ cup (120 milliliters) non-chlorinated water

Instructions

  1. Select a pristine glass container with ample room for fermentation, combining whole wheat or rye flour with filtered water to create a thick, uniform paste.
  2. Whisk the mixture thoroughly, ensuring no dry flour pockets remain, then drape a breathable cloth or lightweight lid over the container to allow natural yeast circulation.
  3. Position the mixture in a stable environment with consistent warmth, avoiding direct sunlight or drafty areas, and let the natural fermentation process commence for approximately one full day.
  4. After the initial 24-hour period, discard half the original mixture and replenish with fresh flour and water, maintaining the same hydration ratio and mixing technique.
  5. Repeat the feeding process daily at consistent times, observing gradual transformation as bubbles emerge and a tangy, slightly sour aroma develops.
  6. Monitor the starter’s growth, seeking a doubling in volume and notable frothy texture, which typically occurs within 5-7 days of consistent feeding.
  7. Test the starter’s readiness by performing a float test: drop a small amount into water, and if it rises and remains buoyant, the culture has reached optimal fermentation and is prepared for bread making.
  8. Once mature, maintain the sourdough starter through regular feedings, storing at room temperature if used frequently or refrigerating for less active periods.

Notes

  • Choose whole wheat or rye flour for a more robust starter with deeper flavor complexity.
  • Use filtered or bottled water to avoid chlorine, which can inhibit wild yeast growth.
  • Mix ingredients thoroughly, ensuring no dry flour clumps remain for consistent fermentation.
  • Keep your starter in a consistent warm environment away from direct sunlight or drafts to promote steady microbial activity.
