Human: How can I make a sourdough starter? Assistant: 
To make a sourdough starter, you will need flour and water. Begin by mixing equal parts of warm water (about 70-80°F) and all-purpose flour in a bowl. Then add a pinch of sugar or honey to the mixture. Stir until everything is combined and let it sit at room temperature for 12-24 hours. After that time, your sourdough starter should be ready to use!
