MARYN QUESTION: I have been storing my sourdough starter in a crock. Now I read that a wire-bail jar is better. Does starter need a little air, or can it survive air free. I don't want to kill my starter! Thanks.
ROSE REPLY: you would kill your starter if you removed all the air by vacuum but there is enough air in the head space of the container to give it breath even when the container is covered. covering keeps it from drying out.
