sourdough starter
Prepare Your Starter. Begin with a well-fed, bubbly sourdough starter. If it’s been a while since you last fed it, give it a good feed and wait until it’s active and full of bubbles.
Spread It Out. Line a baking sheet with parchment paper. With a spatula, spread your sourdough starter thinly across the paper.
Let It Dry. Place the baking sheet in a warm, dry area with good airflow. A sunny spot on the countertop or a barely warm oven (turned off) with the door slightly open can work well.
Break It Up. Once fully dry, the starter should be brittle and easy to crack. Break it into small flakes or grind it into a powder.
Store It Safely. Transfer the dried sourdough flakes or powder into an airtight container, mason jar, or a sealed zip-top bag – a Mason jar is my preference.
