1 1/2    cup                  active sourdough starter
            4        cup                  unbleached flour
            2        tablespoon           sugar
            2        tablespoon           shortening, melted
            1        teaspoon             salt
            1/4      teaspoon             baking soda

           Into a large bowl, sift the dry ingredients, and dig a well in the center
           of the sourdough starter.  Blend the dry mix into the starter from the
           edges with enough flour to knead until smooth and shiny.  Place in greased
           bowl and let rise until almost double.  Shape into 2 loaves and place in
           greased bread pans.  Bake at 375 degrees F until done.
