Shirley's Sourdough Starter

• 2 cups flour
• 2 cups warm water (about 190 degrees)
• 1 fresh yeast cake

1. Mix together all ingredients in a bowl or large jar (nothing metal).
2. Set uncovered (or cover with a double thickness of cheese cloth) in a warm place (about 80 degrees) overnight.
3. Mixture will smell sour and be full of bubbles.
4. Keep your starter in the refrigerator in a glass jar covered with a piece of plastic wrap before screwing on the metal cap or a plastic container.
5. After use, replenish with a proportional amount of flour and water.
