Description

A sweet, resilient, and easy-to-maintain sourdough starter made with instant potato flakes and active dry yeast.


Ingredients

Scale

1 cup warm water (105-110°F)
1/2 cup granulated sugar
3 tablespoons instant potato flakes (plain)
1 packet (2.25 tsp) active dry yeast (for the initial batch only)


Instructions

Étape 1: In a clean glass jar or non-reactive container, combine the warm water, sugar, potato flakes, and yeast.
Étape 2: Stir the mixture thoroughly with a wooden or plastic spoon until the sugar is mostly dissolved.
Étape 3: Cover the jar loosely with a lid or a clean cloth and let it sit at room temperature (70-75°F) for 5 to 8 days.
Étape 4: Stir the starter once daily during this fermentation period. It will become bubbly and develop a sweet, yeasty aroma.
Étape 5: After the initial fermentation, the starter is ready to use. Store it in the refrigerator and feed it every 7-10 days with 1 cup warm water, 1/2 cup sugar, and 3 tbsp potato flakes.

Notes

Always use non-reactive tools (wood, plastic, or silicone) when handling your starter. Avoid metal as it can react with the acidic environment of the fermentation.
