Product Reviews

Love it! I am making einkorn sourdough bread, it’s exactly what I was looking for! -Angel

I LOVE this starter! I have made pancakes twice with it, I have 2 loaves of bread proofing right now, and I plan to try out some pretzels this week. It is so easy to maintain. I keep about a cup in my fridge and I’ve been keeping some out for daily use. LOVE it! Next I plan to freeze some so I will truly never be without sourdough again! -Lauren

Product Q&A

Q.  Can this starter be used with white whole wheat flour, or should I stick with regular white flour?

A.  The San Francisco Sourdough Starter should be fed with regular white flour. Once your starter is well-established and active, you can switch a portion of it to a different type of flour, such as white whole wheat flour. Always retain a portion of your master starter as a back-up.

Q.  Hi.. Just wondering if these Sourdough starters are in a dried form or in a ball of dough of some sort? I’ve tried other cultures from elsewhere that came in a dried format and I’m likely not going to be around when they arrive in the mail.. I just need to inform the neighbor kid to put it in fridge or a cool spot if required (since it’s almost winter here).. Thx!

A.  They are in fact dried! The sourdough starters are fine at room temperature for 6+ months. So even if your neighbor simply put the package in your home where it’s room temperature, it would be fine!

Q.  My starter come up very sour. And the bread was very sour as well. I used the right proportions but somehow it’s really VERY sour. Should the proper starter be sour?

A.  The San Francisco Sourdough Starter makes a traditionally sour bread. To reduce or increase the sourness of your bread, there are several tips in this article: http://www.culturesforhealth.com/how-to-make-truly-sour-sourdough-bread
