We love buying or picking in-season fruit, then jamming (our term for making jam) or canning. The problem is, sometimes we pick or buy, but don't have the time to process it. Here is our solution: the freezer. Freeze the fruit in a box or on a tray. After it is solid, transfer to a ziplock bag, label, and pull out when there is time!
I also love this because most of the canning season is in the summer, when it is hot and when I don't want to be in the kitchen all day. Come fall, I am ready and excited. I grab my bags and off I go. Obviously this doesn't work with all fruit, but it can work with most, especially if it is jam or fruit butters that you are making.
