In a large non-metallic bowl, mix together 1 package active dry yeast, 2 cups warm water and 2 cups all-purpose flour. Leave in bowl or place into a glass jar. Cover loosely
Leave your start in a warm place to ferment, sit your jar or bowl on a cookie sheet in case of overflow. Check daily. This process takes about 4-8 days. This time is dependent upon the temperature and humidity in your kitchen
When your mixture is bubbly and begins to have a pleasant sour smell it is ready for use. *NOTE: If your mixture has a pink, orange or another strange colored tinge to it, THROW IT OUT and start over
Keep your Sourdough start in the refrigerator until ready to use
When you use your starter for baking, always replenish your mixture with equal amounts of flour and water with a pinch of sugar. For example: if you use 1 cup starter; replace 1 cup water and 1 cup flour with a pinch of sugar into your mixture. Mix your starter well and leave on the counter until bubbly again, then replace in the refrigerator
