Grey-ish water floating on top of my sourdough starter?
I have sourdough starter that I got going about 3 weeks ago. Everything looked fine and it smelled perfect so I moved it to the fridge. I wanted to bake a couple of loaves this weekend but when I pulled it out of the fridge it had a layer of water on top that was kind of a weird color... Almost a greyish color? No fuzz anywhere though, I've been good about keeping the container scraped clean to prevent mold. Last year was my first time trying to make sourdough starter but I don't recall it doing this. It smells just fine and looks normal when I stir it up.
Just wondering if it's safe to go ahead and bake with it or should I toss it and start over?
Thansk for your input!
