Freezing Blueberries – Top Tip

Have you ever noticed a cloudy coating on your blueberries as you pick them up? This coating has a name – bloom. This bloom protects the blueberries from pests but it also prevents them from sticking. For this reason, it’s best not to wash them before freezing as you may lose this nonstick coating.


How to Freeze Blueberries

Follow our step-by-step guide for freezing your blueberries and they’ll be just as tasty as when they were fresh. Even better, they don’t lose any of their healthy nutrients either.

  1. Select the blueberries you wish to freeze – they should be ripe and free from any leaves and stalks.
  2. You don’t need to wash your blueberries as you want them to retain their bloom (protective coating). This will ultimately stop them from sticking together in the freezer.
  3. For best results, spread out evenly on a tray and freeze them in this manner.
  4. Once fully frozen, you can divide them up into portion sizes and pop them into freezer bags for your convenience.
  5. Don’t forget to label and date them so you know exactly when you froze them.
  6. Wash them before eating.

Freezing Cooked Or Puréed Blueberries

If you are worried your cooked or puréed blueberries will spoil once frozen, don’t panic. It’s perfectly fine to freeze blueberries using this method which is really handy for those last-minute baby treats or smoothies.

  1. Wash and blend your fruit as required.
  2. You can add sugar to your purée if it’s to be used in sauces or desserts. Or leave as it is for all other purposes.
  3. You can pour into ice cube trays and freeze this way which means it’s super easy to reach for portions as and when required.
  4. Or you can pop into containers suitable for the freezer, ensuring you leave headspace.
