How can I make a sourdough bread starter?
assistant
To make a sourdough bread starter, you will need to combine equal parts of white flour and water in a bowl. Then, mix in some yeast or other leavening agent, such as baking soda, and stir until the mixture is thick and sticky. Finally, cover the bowl with plastic wrap and let it sit at room temperature for about 12 hours. After that time, your starter should be ready to use!
