How Do I Know When My Sourdough Starter Is Ready?
There are three things to do when determining if your sourdough starter is ready for baking:
Look for Bubbles
As your sourdough starter ripens, you’ll begin to notice more bubbles each day, as well as a strong sour smell. You may also see a clear liquid forming on the top. When you feed your starter, you’ll hear a crackly sound as the bubbles pop with mixing.
Check the Volume
An active sourdough starter can quickly double its volume. If you note that the volume has doubled four hours after feeding it, your starter should be ready for baking. To test this, place a piece of tape to mark your starter’s volume and then check back four hours after feeding it.
Will It Float?
Grab the kids for an impromptu science experiment when you test your sourdough starter in water. Place about a teaspoon of the starter into a cup of warm water. If it floats, it should be ready for baking. Even if your starter doesn’t float, it could still be ready; go by the volume test to be sure.
