There are so many great, traditional ways to work with starter, Lin. We never tire of hearing them! In a dry climate, this might work to dry the starter out in much the same way as spreading it out on a cookie sheet. In a more humid climate, however, you could run more of a risk of the starter over-fermenting before it dries. We'd also wonder how it might contaminate the flour it touches. If it comes in contact with a whole bin of flour, it may/may not be worth it. Maybe not things your Grandma worried about, but we'd give them some consideration before giving it a try yourself. Keep us posted! Mollie@KAF
