I made my yeast starter about 24 hours ago and I haven't seen a frothy layer of foam on top like when you make bread starters, but the airlock is bubbling and there is the cake on the bottom. Did I just miss the all the action? I'm assuming if the airlock is bubbling that it must be ok. I just want to make sure it's not dead.
Assuming it's ok, how long should I wait before I brew? I was planning on doing it tomorrow afternoon meaning the starter has been going for 36 hours of so. Do I just pour the entire thing into the batch?
