Step 1

In a large bowl combine Herman Sweet Sourdough Starter, flour, baking soda, salt, baking powder and eggs until well blended.

Step 2

Knead dough in bowl for 5 to 7 minutes, or until mixture is smooth.

Step 3

Let rise in warm place until doubled. Punch down. On a lightly floured surface, press dough into a 10 x 20 inch rectangle. Combine melted margarine, sugar and cinnamon in a small bowl. Spread mixture over dough. Sprinkle with walnuts or raisins, if desired.

Step 4

Starting on long side, roll up dough, jellyroll fashion. Press ends together to make a seam. Cut in 1-inch slices and place in an ungreased, 11x14 inch cake pan. Allow rolls rise to double their size.

Step 5

Bake in a preheated 325 F oven (165 degree C) for 20 to 25 minutes, until lightly browned.
