How to wash frozen berries
Ready to eat as sold. If you are eating them raw and thawed rather than cooking or blending, a quick rinse does no harm.
Washing reduces surface residue and soil. It does not remove systemic compounds taken up into the plant, and no soap, vinegar, or commercial produce wash has been shown to beat 30 seconds of plain running water by a margin worth paying for. Full washing guide.
Buying and storing
- ◆Berries are frozen within hours of picking at peak ripeness, so anthocyanin content holds up better than in fresh berries flown in and shelved for days.
- ◆For smoothies and oatmeal there is no functional difference from fresh, at roughly half the off-season price.
