Dehydrating blueberries is super simple! I really think it's the easiest fruit to dehydrate.
How To Dehydrate Blueberries Step by Step:
Start with fresh sweet blueberries. You might make a note next time you purchase a package as to where they came from. Berries from northern states tend to be sweeter than those from southern states, in my experience. So next time you get some super sweet blueberries make a note as to where they came from so you can know what to look for when you're looking for berries to dehydrate. We're not adding any sugar in the dehydration process so you want to start out with the sweetest ones you can find.
Wash your blueberries.
That's a lot of berries! I have a nine tray Excalibur Dehydrator, and this is about 14 dry pints. I filled up 7 of the trays. Two pints to each tray.
Simply place the berries on the tray.
And place in your dehydrator. There are some directions for dehydrating blueberries that will tell you to take a knife and puncture each one. You can do that if you want. I decided it wasn't worth the time it would take so I leave mine with no punctures.
The down side to not puncturing your berries is that they will take longer to dehydrate. These took about 35 hours.
This is what the blueberries look like when they are dehydrated.
Here I'm using a smaller jar and sealing with a regular mouth attachment to vacuum pack the berries.
I love the FoodSaver attachment because it will fit on the little 4oz jars as well. Here are just enough blueberries for some muffins or perhaps a snack for my boys.
I put the berries in the freezer for two weeks to pasteurize them, then store them in a cool dry place. See, super easy! Buy them. Wash them. Dehydrate them. Eat them. That's it!
