I always wash my fruit before I eat it when I buy it fresh. Recently I’ve been buying frozen bluberries and honestly I sort of like just eating them straight out of the bag (after letting them sit out for a little bit). But I’m wondering - should I be washing the berries before I eat them? If they were fresh I’d absolutely wash them but I’m unsure if this is necessary for frozen.
Best you could do would be a rinse, not sure if trying to use soap would work. It might be difficult to rinse the soap off.
If you try to refreeze they are going to turn into a solid mass though.
