Sour Dough Starter Green?!
I decided to try Kevin Dunden's sour dough starter. The first day was fine, looked and smelled good. I used spring water and US bread flour.
This evening I see some green on the top of the starter and it doesn't smell very good. I'm wondering if it is mold?
Should I be concerned? Do I need to throw it out or can I remove the top layer and hope the green doesn't return?
Thanks for any advice.
