This is one of those projects that was really so easy it shouldn't deserve its own post, but here it is anyway. Dehydrating blueberries.
First, get some blueberries. It really doesn't matter how many, but the more the merrier. Wash them and pick out any that are squishy or bad.
Now get a pot of water boiling. If you've got a collander that can fit into a pot, use that pot. It doesn't have to be too big, but you'll have to dip the blueberries in and pull them out, so get a pot big enough to do that. I only had a little collander that could go in the boiling water so it was a little awkward, but it worked. I just did then a few at a time. It would have been really quick if I could have dunked the whole bunch at once. I put a hot pad on after this batch.
The blueberries need their skin cracked so the moisture can escape and they can dry. You're going to crack the skin by dipping them in the boiling water for 15-30 seconds and then pulling them out. It's easier than putting a little slice in each berry for sure. The berries darken up in the water.
After the berries are out of the water, put them on your dehydrator trays, spread them out so they're not all piled on each other, and dry them.
In my Excalibur I dried them at 135 degrees until they were chewy but not soft. It took overnight plus about 3 more hours the next morning--probably 16 hours total.
They can be used in pancakes, muffins, granola, etc. or just eaten plain. I had to hide these because they kept getting eaten. Yummy and super easy way to preserve blueberries. Little wrinkled balls of goodness.
Enjoy your dehydrated blueberries as long as you can keep them hidden from the little snackers. :)
