Put an elastic on your sourdough jar to keep track of the fermentation process. When making sourdough, it's important to know when the starter has doubled in size (or tripled!), which indicates that it's ready to be used for baking. By placing an elastic band around the jar at the level of the starter after it's been fed, you can easily track the progress of the feeding process.

Each package contains 10 elastics
