If you have a persimmon tree (or at least a bunch of persimmons), how about drying them the traditional Japanese way, by skinning and hanging to air-dry? They turn into jam-like dates. It's called Hoshigaki, and it's fun AND delicious.
This is my favorite time of the year. It’s cranberry season. Over the past 7 years I have been foraging for wild cranberries. It has become a tradition for me and a few friends. Every year, I make wild cranberry sauce for Thanksgiving.
