Potato sourdough starter produces a milder sourdough bread than the stronger rye or wheat starters. This starter is also inexpensive to make, using only three medium potatoes. The bread flour can be replaced with all-purpose, wheat, or rye flour, making it a flexible recipe that can be pulled together easily.
What’s best about this potato sourdough starter is that you restart it every two weeks, preventing the yeast from becoming too sour; you can also restart the starter from scratch or by using a cup of the original starter.
When making sourdough bread, remember that 1 cup of potato sourdough starter can be used in place of 1 package of active dry yeast.
"I’m always looking for ways to use my leftover potato scraps, and this recipe is perfect for that. If you're using an immersion blender, skip the step of draining the potatoes and just blend the potatoes in the pot with the cooking water. I used the starter to make sourdough focaccia and cinnamon rolls." —Renae Wilson
3 medium potatoes
4 cups water
2 1/4 teaspoons active dry yeast (or one 0.25-ounce packet)
1 cup warm water
1 cup bread flour
1/3 cup white sugar
1 1/2 tablespoons salt
Gather the ingredients.
Peel and cube the potatoes.
In a large pot, boil the potatoes in 4 cups of water until soft, about 30 minutes.
Set a colander over a large bowl and drain the potatoes. You’ll use both the potato water and the potatoes in the starter, so be sure to reserve the potato water.
Return the potatoes to the pot and mash using a potato masher or immersion blender.
Add the mashed potatoes to the potato water. Stir and set aside to cool until lukewarm.
Stir in the yeast and warm water. Then mix in the bread flour, sugar, and salt.
Cover the bowl with a clean kitchen towel and let it sit for 24 hours at room temperature.
Pour the starter into a large jar or 2 smaller jars, cover, and store in the refrigerator. It is now ready to use in your favorite sourdough bread recipe. Enjoy.
- You can use the potato sourdough starter in recipes calling for sourdough starter; just replace the wheat-based starter with an equivalent amount of the potato starter. For recipes calling for active dry yeast, use 1 cup of the potato starter in place of 1 (1/4 ounce) package of yeast. Try making sourdough pizza crust, bread rolls, or a loaf of bread.
- Use the starter in sourdough recipes within two weeks. At the end of two weeks, make a new starter from scratch, or follow the starter directions, replacing the dry yeast with 1 cup of leftover starter.
- You can also store in large plastic containers in the refrigerator.
- If the liquid separates from the starter as it sits, just give it a stir to bring the mixture back together before using.
- This recipe makes about 6 cups of starter. If you need less, feel free to cut the recipe in half.
