Sourdough Starter: A Bubbly Leaven with Culinary and Health Benefits
A sourdough starter that is very bubbly is an active and healthy culture of wild yeast and beneficial bacteria that is used in the fermentation of bread. When a sourdough starter is very bubbly, it indicates a high level of activity and is a sign that the starter is ready to be used. An example of a sourdough starter that is very bubbly is when it has doubled or tripled in volume and is full of air bubbles. This bubbly activity is a result of the microorganisms in the starter consuming the sugars in the flour and water and producing carbon dioxide gas as a byproduct.
