Gluten Free Sourdough Starter

So you want to make a gluten free sourdough starter but you don’t know where to start. You have scoured the internet for ideas but every recipe you find wants you to make your own flour blend and precisely weigh out ingredients and that just feels too time consuming (and expensive) for you to take on. But now you have stumbled upon my recipe – I have spent much of this year testing out gluten free sourdough and learning everything I can so that I can create an easy, accessible, and affordable sourdough starter and loaf recipe for you!

For this recipe, you just need a bag of the King Arthur Gluten-Free Measure for Measure flour, water, and a large mason jar. I recommend that you use a rubber spatula for mixing instead of a metal spoon. When covering your mason jar, you need to make sure that the cover is breathable, so opt for a paper towel or cloth to secure to the top with a rubber band.

What you need:

King Arthur Measure for Measure Gluten Free Flour


Large Mason Jar

Cloth or Paper Towel

Rubber band

Rubber Spatula

Day 1: Combine 1 cup of flour and ¾ cup room temperature water in a large clean mason jar. Mix together and cover with a thin dish towel or paper towel. Set aside in a dark warm place.

Day 2-5: On each day, discard half of the starter and add ½ cup of flour and ⅓ cup room temperature water to the jar. Repeat.

Day 6 & 7: Discard half of the starter and feed with ⅓ cup flour and ¼ cup room temperature water. You will do this twice a day on both days.

Day 8: You are ready to bake! 6 hours before you plan to use your starter, discard a portion of the starter and feed with ½ cup flour and ⅓ cup water. Once it has reached its peak in fermentation (you will see lots of bubbles), it will be ready to bake with!

To maintain your starter, feed it a little bit each day, or keep it in the fridge to slow fermentation until you are ready to use again!


Can you keep the discard or throw it out

During the first week, you need to throw it out but after it is active + ready to bake with you can keep the discard

It was on the top of the starter, so I tossed it! I’m on day 9 of a new starter though. Should I continue to feed and discard?
