This recipe guides you through creating an active sourdough starter from scratch using only flour and water. Over several days, you will nourish a wild yeast culture through regular feeding and discarding, developing a robust leavening agent for baking artisan breads.
Water quality is paramount; always use bottled, filtered, or de-chlorinated water to avoid inhibiting yeast activity. Maintaining a consistent temperature, ideally between 70-78°F (21-26°C), is crucial for robust starter development. Using a mix of whole grain flour initially can accelerate yeast colonization due to higher nutrient content. Don't be discouraged by initial inactivity; patience is key. Look for consistent doubling in size, bubbly texture, and a pleasant tangy aroma as signs of a healthy, active starter ready for baking.
