Knead 1 minute.) Lightly flour large bowl and add sponge. Cover with towel. Let sponge rise in draft free area until doubled, about two hours. Arrange remaining 3 cups flour in mound on work surface and make well in center. Add raised sponge to well and pull to form well in sponge. Add remaining 1 cup water, 3 tablespoons oil and salt to well in sponge. Knead mixtures together until smooth and elastic dough forms, 8 to 10 minutes. (Can also be prepared in processor.
