Sourdough Starter Bubbling But Not Rising: Understanding and Troubleshooting a Common Baking Issue
Sourdough starter bubbling but not rising is a common problem faced by bakers using this natural leavening agent. This occurs when the starter, a mixture of flour, water, and wild yeast, exhibits signs of activity, such as bubbling and expansion, but fails to rise as expected. For instance, a baker may observe a bubbly and active starter that does not double in size after several hours or overnight fermentation.
