Sourdough Culture
["1 c. milk", "1 c. flour"]
["Allow milk to stand in a warm place for 24 hours.", "Using a wooden spoon, stir in flour.", "Allow to stand in a warm place until it forms bubbles and becomes very sour.", "When ready, place in a large, loosely covered bowl and place in refrigerator.", "Never use metal bowls or utensils when working with sourdough."]
