Potato Sourdough Starter
• 3 medium potatoes (peeled and cubed)
• 4 cups water (for boiling)
• 2 1/4 teaspoons active dry yeast (1 pkg)
• 1 cup water (warm)
• 1 cup bread flour
• 1/3 cup sugar
• 1 1/2 tablespoons salt
Steps to Make It
Peel and cube 3 potatoes. Boil potatoes in 4 cups of water until soft.
You’ll be using both the potato water and the potatoes in the starter. Drain the liquid off into a large bowl. Mash the potatoes and add mashed potatoes to the liquid. Stir and set aside until lukewarm.
After the liquid potatoes are slightly warm, stir in yeast and warm water.
Mix in the remaining ingredients.
Cover the bowl with a clean kitchen cloth and let sit for 24 hours at room temperature.
Pour starter into large jar or jars, cover, and store in the refrigerator. In the summertime, we use all our jars for canning and dried fruits, so we store our sourdough starters in large plastic containers in the refrigerator.
Use starter as called for in sourdough recipes. 1 cup of potato sourdough starter can be used in place of 1 package active dry yeast.
Use the starter up within 2 weeks. At the end of two weeks, make a new starter from scratch or follow the starter directions above, replacing the dry yeast with 1 cup of leftover starter.
