Here is one of my favorite sourdough breads. I do it in the bread machine since I'm lazy, but turns out pretty darn good. 2 1/2 - 3 Cups flour 1/6 Cup instant dry milk (I skip this if I don't have any and doesn't seem to matter) 1 1/2 tsp sugar 1/2 tsp salt 1/2 package dry yeast 1/2 Cup warm water 1 Tbsp butter softened 3/4 cup sourdough starter I just put this into my bread machine and follow it's inst. I use the large loaf, med (browness) setting. Purists might not care for this since it does use yeast but I like the end results.
