STARTER FEED: Mix well and add to starter. Let stand out of refrigerator all day (5 to 12 hours). Mixture will be bubbly. Take out 1 cup to make bread and return starter to refrigerator. Keep in refrigerator 3 to 5 days and feed again. If not making bread after feeding starter, throw away 1 cup to avoid depleting your starter.

SOURDOUGH BREAD: Combine above ingredients and make a stiff batter. grease another bowl. Put dough in and turn over oily side on top. Cover with foil and let stand overnight. (Do not refrigerate.) The next morning, punch dough down. Divide into thirds. Knead each part on floured surface 8 to 10 times. Grease 3 loaf pans and turn each loaf over in pan so it has oil on both sides. Let rise in pans 4 or 5 hours. (All day is all right.) Cover with waxed paper. Bake at 350 degrees for 30 to 35 minutes. Remove and brush with butter. Cool on rack. Wrap well and store. Refrigerate. Bread may be frozen.
