Hi all. Can someone please tell me how to revive my starter? I've used it a couple of times and it has performed beautifully. However, this morning it simply won't bubble up and when I drop a tsp. Into water it sinks to the bottom. I just don't know what I did wrong and I don't know how to fix it. Thank you so much.
