Produce Overload: Dehydrating Blueberries

You can only do so much with blueberries in terms of preserving. Ive done as much blueberry jam as I like, Ive frozen over 30L and that left me with one other unexplored method - to dehydrate them! Im fortunate to have a dehydrator, but I haven't had the opportunity to use it much. I read online that they take a long time to dry (and a takes a lot of berried if you want something as an end result)! So I spread the berries on the trays (with the "roll-up" tray at the bottom - to catch the ones that slip through), I stacked the trays and set the dehydrator to 115oF. Then I left it about 2 days. I checked it periodically, taking out the berries that were completely hardened. It seemed that the berry skin held moisture in, which took that much longer for them to dry. When they were all hard, I put them into glass jars to enjoy this winter.  Im hoping that they keep well and won't mould. It would be a shame to lose any. They turn out sweet and chewy - and make a wonderful snack. Almost beats candy!
