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.

Great Hostess Gift for Baker

I gave this as a hostess gift to a friend that loves to bake. They loved it, and I loved getting some of the bread she baked.

wonderful Results

I ha 've had a sour dough starter since the 60's but it bit the dust when I moved to East Texas..too much iron in the water!. I TRIED YOUR STARTER AND IT WAS A PERFECT MATCH.

Perfect sourdough

Received my order quickly, and started it the next day. Took right off without a hitch, Been making bread for a few days now, and has been wonderfull!

Great Starter

This stuff took right off and got very active quickly. It took less time than advertised. The best news is that it makes sour sourdough bread like the stuff I am used to in San Francisco area where I live. I highly recommend it.
