I was in the process of preparing bread. I had built my Leaven for use in the next morning, and I got a call that a relative was dying. I put the Leaven in a sealed glass jar and into the frig and left. Now the time has passed about 2 weeks.
Is there any chance of reviving the levan I have prepaired?
I agre with madauar. However, when going away for longer than a week, put your starter in the freezer. Mine took a week of nurturing when I defrosted them (I keep two), but then they were back to their old chipper selves.
