I made some biga and used it once. There were some left overs, so I added more flour and a bit of water. There is now a layer of water on top of it, after I left it for a few days.
How do I know if it is off?
Update: I think I'm making alcohol. I opened it and it smells like alcohol. I've mixed in the "water" layer on top and added more flour.
Lets see what happens?
