2 Cup(s) all purpose flour
2 1/4 Teaspoon(s) active dry yeast
2 Cup(s) warm water
In a 2-quart or larger container, combine all-purpose flour and yeast. Gradually add water to dry ingredients and beat until smooth. Cover loosely; let stand in a warm place until bubbly and sour smelling, about 2 to 4 days. Transfer to a 2-quart or larger plastic container with tight-fitting lid. Refrigerate until ready to use.
To keep starter alive: Once a week stir in 1 tablespoon all-purpose flour and 1 tablespoon lukewarm water (105 to 115oF). Beat until smooth. Cover loosely and let stand until bubbly, 12 to 24 hours. Cover tightly; refrigerate until ready to use.
To replenish starter: For each 3/4 cup [1 1/4 cups] of starter used, add 2/3 cup [1 cup] all-purpose flour and 2/3 cup [1 cup] lukewarm water (105 to 115oF). Beat until smooth. Cover loosely and let stand until bubbly, 12 to 24 hours. Use or cover tightly and refrigerate until ready to use.
