So a couple of weeks back I made a yeast starter but realized afterwards that I didn't use enough DME for the amount of water I used. I placed the starter in the fridge to let the yeast settle back down so I could use it in another starter. Today I made a new starter and added it to my flask after draining the old liquid off of it. I left the house for a few hours and when I came back the foil I had loosely around the top was off and I had what appeared to be dough on the outside of the flask. Is this starter ruined? Have I lost to much yeast? Probably not safe to use what is left in there.
