People have resuscitated starters
No problem! You can dry out your starter by spreading it in a thin layer on a parchment or foil-lined sheet pan and leaving it out. Keep the dried starter in a container and rehydrate it when you want to use it again by dissolving the dried starter in warm water and feeding it at regular intervals like you would normally. People have resuscitated starters from 4,500 years ago! Like I said, it's hard to kill.
