I recommend flash freezing them first rather than just dumping them all together in a container and tossing in the freezer. They will freeze all into one big glob and make it impossible to take out only a few at a time.
Flash freezing is the technique where you place foods to be frozen on a baking tray in a flat individual layer and freeze till each food item is frozen, then remove and store in a freezer container. Now they can be grabbed by the handful if needed.
- Line baking tray with parchment paper.
- Spread berries in a single layer
- Freeze for about 2 hours till berries are frozen solid.
- Store berries in an airtight container in freezer for up to a year.
