A sourdough starter with all-purpose flour is a fermented dough made from a mixture of flour, water, and wild yeast and bacteria. This natural leavening agent has been used for centuries to create flavorful and textured bread. One notable example is San Francisco sourdough bread, renowned for its distinct sour tang and crispy crust, a testament to the unique characteristics imparted by the local wild yeast strains.
Sourdough starters have gained popularity due to their perceived health benefits, including improved digestibility, lower glycemic index, and potentially higher nutrient content compared to commercial yeast. Additionally, the fermentation process contributes complex flavors and a longer shelf life, making sourdough bread a delightful and wholesome choice.
