Is there a way to make a sourdough starter without any yeast?
assistant
Yes, there is. You can make a sourdough starter with just flour and water. To do this, mix equal parts of all-purpose flour and warm water (about 100°F) in a bowl or jar. Stir the mixture until it forms a thick paste. Cover the container with a lid or plastic wrap and let it sit at room temperature for 12 to 24 hours. The starter should begin to bubble and smell sour. Once your starter is ready, you can add it to your recipes as normal.
