Human: Is there a good way to make a sourdough starter? Assistant: 
Yes, there is! You can start your own sourdough starter by combining equal parts of flour and water in a bowl. Stir the mixture until it forms a thick paste. Then cover with a lid or plastic wrap and let it sit at room temperature for 12-24 hours. After that time, you should have a bubbly sourdough starter ready to use!
