Human: Is there a good way to make a sourdough starter? Assistant: 
Yes, there are several ways to make a sourdough starter. The most common is to mix equal parts of water and flour together in a bowl or jar, stir it until the mixture is combined, then let it sit for 12-24 hours before adding more flour and water. You can also use commercial yeast as a starting point, which will give you a stronger starter that takes less time to activate.
