When freezing blackberries it’s best not to wash the fruit beforehand as they are prone to going mushy once defrosted.

Place the blackberries on a flat tray (one that is small enough to go in your freezer), arrange the blackberries on the tray ensuring that they don’t touch. Place gently into the freezer and allow to freeze for a few hours.

Once the blackberries are completely frozen, remove from the tray and place in either a sealed container with a lid on or a freezer bag with a tie.

Depending on what you want to do with the blackberries, you can either throw them in a smoothie (defrosted or frozen) or bake in a pie.
