I think Yeoeleven has tried this - it doesn't need freezing, or even refrigeration - some of the meals he had were delicious - lamb shanks and quite a few others. Don't know if the same brand, but sounds the same product. He was very happy with it.

We had some a while back. Loved all but the shanks, which we found to be greasy and not so tasty. They are dead easy to prepare just chuck them in boiling water for a while and bingo. We also found them expensive.

Cheers
