Ingredients

1 pkg. yeast
2 1/2 c. warm water
2 c. all-purpose flour

Dissolve yeast in 1/2 cup water. Stir in rest of water, flour and sugar. Beat until smooth. Cover with thin cloth. Let stand at room temperature for 5 to 10 minutes, stirring 2 or 3 times a day. Cover and refrigerate until ready to use. To keep starter going, add 3/4 cup water, 3/4 cup flour and 1 teaspoon sugar to remaining starter after some is used. Let stand at room temperature until bubbly and well fermented, at least 1 day. Cover and refrigerate until ready to use again. If not used in 10 days, add 1 teaspoon sugar every 10 days.
