1/4 cup brown sugar
2 teaspoons salt
4 to 4 1/2 cups flour

Soften yeast in 1/4 cup warm water; pour remaining 1 cup water over sugar, salt and butter. Stir in 2 cups flour, starter, oats and softened yeast. Stir in enough additional flour to make stiff dough. Knead on floured board until smooth. Make dough into ball.
