- Use fresh blueberries that are completely dry when you pop them in the freezer.
- You can freeze the blueberries without rinsing if you want. Just make sure to rinse them just before use.
- If you prefer to rinse the blueberries first, dry them well with paper towels,
- Once your blueberries are dry; line the cookie sheet or pan with plastic wrap (or other lining), then add one layer of blueberries. Try to see that they’re not touching; you want to freeze them individually. Put the pan on a level freezer shelf and freeze for 30 minutes. This way the blueberries won’t stick together and you can remove just the portion you need.
- Remove the pan and place the berries into your container or plastic bag. Immediately return the blueberries to the freezer.
- Blueberries will keep for up to 6 months in the freezer.
