How To Freeze Blueberries
With just a few easy steps and a couple of kitchen items, you can easily freeze fresh blueberries, thereby extending the shelf life of this seasonal fruit!
Baking sheet/wire rack
I do not recommend washing organic blueberries. Instead, rinse your blueberries only when you plan on actually using them. The blueberries have a naturally waxy protective coating. This coating protects them from pests and bacteria, but it is also naturally nonstick.
If you want to rinse your blueberries, make sure you air-dry them before freezing, otherwise, the berries may stick to each other.
Pick out any green or blackened blueberries and make sure to remove the stems.
Place the blueberries on a baking sheet or a wire rack lined with parchment paper.
Freeze the blueberries for 2-4 hours or until firm.
Once frozen transfer the blueberries into a freezer-friendly container.
Always freeze your blueberries on a flat surface. Freezing the blueberries in a ziplock bag or a container will just make them stick together. Do not keep the blueberries too long on the baking sheet. Too much exposure to the ice-cold air may cause freeze burns. Once they are frozen, store them in a freezer-friendly container, protected from the direct impact of the freezer.
How long to store? Frozen blueberries will keep good for up to 6 months, but can be stored for up to 10 months.
