<human>:  How do I make a sourdough starter?
<bot>: The easiest way to make a sourdough starter is to mix equal parts flour and water in a bowl or jar. Allow the mixture to sit, uncovered, for about 2-4 days, which will allow the wild yeast to start feeding. During this time, stir the mixture a few times a day and add more flour and water as needed to keep it at a thick pancake batter consistency. Once you begin to see bubbles and a slightly sour smell, your sourdough starter is ready to use. Enjoy!
