I killed it

Baking a batch of bread with my sourdough starter.  I do this every week.  I was preheating the oven and forgot that I was storing the starter in there after feeding it.  It's dead...I think I can salvage my glass bowl if I can peel off the melted plastic wrap.  So sad.  I'd been nurturing that starter since November and it was getting sooooo good.

Never preheat an oven before removing what's in it first.
