bread starter- sour dough - Bread Machine Crusty Sourdough Bread -- I've made 4 loaves of this in the past 2 days. One for a recipe, two for other family members, and the last one is for us. Great texture, nice taste, a good recipe to add to my book. Takes a little time (about a week for the starter to sour), but not a lot of hands on! Our family loves it!
