San Francisco Style Sourdough Starter

Great starter, working well for us

Makes great bread and sourdough pancakes

Second try was the charm

Activation was not going well and you replaced the starter kit and following instructions the starter after 5 or 6 days suddenly became very active and is working well. Thanks for great support and followup!!


San Francisco Sourdough Starter


Wonderful sourdough starter. I just finished getting it going. It has wonderful bubbles and a very good clean fermented smell. I can't wait it make pizza crust tomorrow night. Looking forward to lots of good recipes to try.
