Can you tell me how to make a sour dough starter?
assistant
1.  Mix equal parts of whole wheat flour and water in a bowl or container with a lid.
2.  Allow the mixture to sit at room temperature for about 8 hours, until it begins to bubble and smell sour.
3.  Stir the mixture every few hours and add more flour and water as needed so that the consistency is thick but still pourable.
4.  Once your starter has developed a good sour flavor, store it in an airtight container in the refrigerator.
