I bought about 1.2kg of frozen raspberries with the intention of using them yesterday, but it turns out I won't need them for another couple of weeks. I had let them thaw but have put them in the fridge since I realised my mistake.

Am I able to refreeze the berries or should I find some immediate use for them?

What are the risks / consequences if I do refreeze?

Basically, you can refreeze the raspberries.
When a fruit or veg. is frozen, the water inside the plant cell expands, and bursts the cell wall, which is why there is so much 'juice' when you thaw. If you refreeze, you can be sure that the raspberries will freeze into a giant block. If you are using them to make a sauce or a jam, this is not significant. That being said, if you are using frozen raspberries in the first place, you are obviously not looking for a perfectly intact raspberry, you are using them for some other purpose. Therefor, refreezing is no big deal. I recently answered another question about freezing and refreezing, and how it is basically a myth that it renders the refrozen product inedible. Any time you freeze you know that you are not going to get 'exactly' the same product when you thaw it, and the same goes with refreezing, there is always a 'slight' degredation of the product with each successive freeze (do you like my liberal usage of quotes?) You won't poison yourself or anything like that, you should have no worries.

That being said, what are you doing with the berries? Certainly a refrozen raspberry should be no worse that a raspberry frozen once.

  • That's the reassurance I was looking for, thanks! I'm making a Raspberry Ale, so the fruit does not need to be intact at all. – Mark McDonald Oct 16 '11 at 23:04
