Depending on how hot your starter got, you can try peeling off the top layer of skin that likely formed (you're not the first baker to have your sourdough inadvertently heated!) and adding a pinch of yeast. It may be a lost cause, but it worth giving it a few feedings to see if you can revive it. Reading the blog on Drying Sourdough Starter may also give you a few ideas about reviving it. Good luck, our fingers are crossed! You know where to go if you need a replacement...Kye@KAF
