I have two sourdough starters going one I keep in the frig. the other on the counter. The one on the counter has all of a sudden turned yellow. It was fine yesterday and when I went to feed it today it had a crusty film on top and it is a pale yellow. Is it still good?
Neither one of my starters has hooch is that normal? They have been going for about 3 to 4 weeks. They also are not very sour smelling. Will this just mean the bread wont be very sour? I got the start from a friend I used it and the bread was great. I saved some to do the two starters I have. Thank you for any help
