Did I Kill My Starter?
The most common question I hear about sourdough starters is how to create one. There are a lot of good threads on that here, and many people have reported success with one or another of the methods described in these pages.
The question I hear next most often is, "Did I kill my starter?" This usually happens because the starter has turned a funky color, and maybe started to smell funny, after being either underfed or neglected.
The answer I give, and one you'll read over and over in these pages, is that it's nearly impossible to kill a healthy starter, and that a starter can suffer a lot of abuse and neglect and still bounce back.
As if to prove this theory, I recently neglected my starter for about a month. Check out this post [1] to read about my experience and see before and after pictures of my neglected starter.
And to answer your question, no, chances are you didn't kill your starter.
