Sourdough Starter

Sourdough Starter

3 tablespoons instant mashed potato flakes

3 tablespoons sugar

2 1/4 teaspoons active dry yeast

1 cup warm water (nonchlorinated)

Combine the instant potatoes, sugar, yeast, and warm water in a covered container. Let the starter sit on the counter for 5 days, stirring daily with a wooden spoon.


On the morning of the 5th day, feed the starter with 3 tablespoons instant potatoes, 3 tablespoons sugar, and 1 cup warm water. In the evening, take out 1 cup of the starter to use in a sourdough recipe. Refrigerate the remaining starter.


Every 5 days, feed the starter 3 tablespoons instant potatoes, 3 tablespoons sugar, and 1 cup warm water. If starter is to be used in a recipe, let the fed starter rest at room temperature 6 hours before use. If starter is not being used in a recipe, keep refrigerated and discard 1 cup of starter after each feeding.
