How to Choose the Right Blueberries

We’re using highbush blueberries, which are a little bit bigger than the wild blueberries you might be used to. These bigger blueberries are perfect for dehydrating because they don’t turn into little rocks when they’re dried out.

We’ll be using these dried blueberries for trail mixes, cereal, and yogurt, and just snacking on them. They’re delicious! Let’s get started.

Cleaning the Blueberries

The first step is to make sure our blueberries are super clean. To do this, we’re going to give them a little vinegar bath. We’re using two tablespoons of vinegar in a big bowl.

You want to make sure that all the blueberries are covered in the vinegar. This is really important, especially if you’re buying blueberries from the grocery store. But if you’re growing them yourself and you know that there are no chemicals on them, then you can skip this step.

We’re going to let the blueberries sit in the vinegar water for about three or four minutes. We’ll move them around and make sure they’re getting nice and washed. We’re agitating them to knock anything off, like stems or tiny needles.

Drying the Blueberries

After giving the blueberries a nice wash, we’re going to strain them out and give them a good rinse with filtered water. We don’t like to use tap water because it has fluoride and chlorine in it. We’re just going to give the blueberries a really good rinse and try not to smush them up too much.

Now that our blueberries are nice and clean, we’re going to take them and lay them out on a towel. This will dry them up a little bit so they’re not wet to the touch. We’ll spread them out and roll them around a little. If you see any pieces of stem or flowers, we’ll just pop them off.

You don’t want to eat the stems because they’re not as tasty as the berries. If you see any funky berries, you can grab them out now.

We’re going to grab another towel and throw it on top of the blueberries. We’ll roll them around just to get the excess water off. We’re using a thicker towel on the bottom so that we can roll them around good and get as much water off as possible. The more water that’s on the blueberries, the longer they’ll take to dry.

Now that we’ve got most of the water off, we’re going to get the blueberries in the dehydrator. We’re going to take our towel off and fill up the trays. We don’t want the blueberries on top of each other because we want good air circulation.

We’re going to finish loading up the trays now.

Dehydrating Blueberries Temperature

We’re gonna set our dehydrator to 135 degrees, which is right about in the middle. Then we’re gonna turn it on and let it run for probably 10-15 hours before we give it a good check.

After about 15 hours this time, our blueberries are done. They took a little longer to dry, but they’re crispy now, which is how I like them for granola. They’re perfect! That’s it, dehydrated blueberries. We’re gonna let these cool down to room temperature so we don’t get any condensation. Then we’ll put them in a glass jar and they’ll keep for a really, really long time.

And that’s it! We can’t wait to use these dried blueberries in our trail mixes and cereal. They’re going to be so delicious!
