I am brand new here and have a question already. I began a new starter about three days ago and have fed it each day with very nice results. However tonight It has developed a brown liquid on the surface with a much more sour odor. I'm not particularly worried about it, but I would appreciate your advice on whether I should stir it in during the next feeding or if I should simply pitch that liquid and continue feeding normally.
For what it's worth, I have been keeping it covered in a closed oven with the light on and was just preparing to move it to the refrigerator after this next feeding.
