Starter in TROUBLE!!!
Hi Everyone, I'm in need of your talent, experience and knowledge. I recently transferred my 5 year old starter to a new glass container from a plastic one. I fed it and put it in the fridge. I took it out a week later planning to feed it again prior to using it and when I opened the jar, I was greeted by a pretty bad, rotten-egg smell. It's never smelled like this. I threw out most of it and fed it again, next time I opened it, same thing. I allowed it to rise at room temperature so I could monitor it's progress and noticed an uneven rise. Basically two strata, one rose a lot the other didn't. I'm worried I've got some undesirables making themselves comfortable in my starter. Any thoughts on how to clean up my starter? I'm thinking maybe a bit of pineapple juice?
Thanks in advance for your thoughts.
