How can I make a sourdough starter?
assistant
To make a sourdough starter, you will need to mix equal parts of water and flour together in a bowl. Allow the mixture to sit for at least 12 hours or overnight, then add equal parts of new flour and water. Continue this process every 12-24 hours until your sourdough is active and bubbly. You can also use commercial yeast instead of baking soda if desired.
