Yesterday I started the starter from Bread Baker's Apprentice. Today when I added the second helping of water and flour I noticed some bubbles in the Day 1 mixture. I mixed in the new flour and water and marked on the side of the jar at the level of the dough. In the book Reinhart says it could maybe rise 50% by tomorrow. Well it has already risen that much in about 4 hours. I have only started a starter one other time and it seemed to take several days to do anything. Is everything alright? Thanks
update: now it has been about six hours and it is coming out the top of the 4c mason jar. I guess i am just going to divide it and add the 3rd day four and water.
Does anyone know how this could be happening so quickly? Or any advice on what i should do?
