Because we were away from home for the whole month of June and because I didn’t want to bother anyone with this huge responsibility of catering for my sourdough, I dried a good bunch of him before we left. I did this only once so far, when we were away last November and back then it took about a day to revive him.
Today I added some water, fed a little flour and put him on the shelf. No signs of life so far, but I’m pretty optimistic that it will work again this time.
Fingers are crossed.
