I decided to make my own Sourdough Recipe with rich Buttermilk, and I have entered this into my personal recipes. I developed this recipe which has worked out well from the 1st loaf, and just seems "fool-proof", and very tasty. Once your Sourdough is the flavor you like best, you can jar it and put it into the refrigerator in 10 ounce portions and use a complete jar each loaf you make in the breadmaker. VERY QUICK and SO EASY!
