Here's how to properly store blueberries

To prolong the shelf life of blueberries, follow Washington State University's simple guide to freezing them. Firstly, give the blueberries a good rinse and ensure they're completely dry before freezing. It's vital to dry them properly to stop the berries from sticking together.

Next, spread the washed and dried blueberries out in a single layer on a baking tray. This helps keep the berries separate and stops them from clumping together.

Then, pop the baking tray into the freezer and let the berries freeze until they're solid. Once they're frozen, move the blueberries into an airtight container or freezer bag for long-term storage.
