Description

Discover the secret to a highly active, robust, and forgiving sourdough starter with this ultimate potato flake recipe. Perfect for beginners and seasoned bakers, this starter offers unparalleled vigor and a subtle flavor enhancement to all your sourdough creations.


Ingredients

Unbleached all-purpose flour
Instant potato flakes (unseasoned)
Filtered water


Instructions

Step 1: In a clean glass jar (1-quart capacity), combine 1/2 cup (60g) unbleached all-purpose flour, 1/4 cup (20g) instant potato flakes, and 1/2 cup (120g) filtered warm water (80-85°F / 27-29°C).
Step 2: Mix thoroughly with a non-metal spoon until no dry clumps remain. The mixture will be thick.
Step 3: Loosely cover the jar with a lid, plastic wrap, or a breathable cloth secured with a rubber band.
Step 4: Place the jar in a warm spot (70-75°F / 21-24°C) for 24 hours.
Step 5: After 24 hours, discard all but 1/4 cup (approximately 50g) of your starter.
Step 6: Add 1/2 cup (60g) unbleached all-purpose flour, 1/4 cup (20g) instant potato flakes, and 1/2 cup (120g) filtered warm water to the remaining starter.
Step 7: Mix well until fully incorporated. Loosely cover and return to your warm spot for another 24 hours. Repeat this feeding process (Steps 5-7) daily for 5-6 more days.
Step 8: By Day 7, your starter should be very active, doubling or tripling in size within 4-8 hours after feeding, with a pleasant tangy aroma. It is now ready for baking! To maintain, feed once a week if stored in the refrigerator, allowing it to warm and bubble before returning it.

Notes

Ensure you use unbleached flour and unseasoned instant potato flakes. Filtered water is crucial to avoid chlorine. A consistent warm temperature (70-75°F) will help your starter thrive. Don't be afraid to discard; it's essential for a strong, healthy starter. Once active, store in the fridge and feed weekly, bringing to room temperature and allowing it to bubble before returning.
