How to Feed Sourdough Starter

Bring Starter to Room Temperature: If your starter is refrigerated, remove it from the refrigerator a few hours or the night before to come to room temperature. If your starter is at room temperature, you’ll want to feed it daily or at least every other day to keep it bubbly and happy.

Feed the Starter: Using a kitchen scale to weigh in grams, discard all but 100 grams of your starter in your glass jar. Add 100 grams flour and 100 grams water and stir thoroughly with a silicone spatula to combine.

Let it Rise: Scrape down the sides of the jar, cover with a loose-fitting lid, place a rubber band on the jar to track how far the starter has risen, and let it grow at room temperature (70-75 ̊F). Once it has at least doubled in volume (4-6 hours), it is considered 'active sourdough starter' and you can use it to make sourdough recipes. Once it falls and is no longer active, you can repeat the feeding process in step 2.
