That way it's not some random internet schmo's opinion. =D
Thanks for the link, it's an interesting read. I have a query though (and I'm not questioning the validity of the information, I just think I am not reading it correctly).
In the section "When Food is Safe to Refreeze" it says:
"If food is safe to eat, it's safe to refreeze."
I don't understand this. If I had food in the freezer, and it thawed, I would eat it. Say I had a chicken breast. It was frozen, now it isn't. As long as it happened within a reasonable space of time, that food is safe to eat - it would be just as if I had taken the meat out of the freezer and left it to defrost on the counter (I'm in the UK, so air temperature is not an issue).
Now, that food - which is safe to eat - is not safe to refreeze, I don't believe. Food can be frozen and thawed safely only once, UNLESS you change it's state ie. cook it. Then it can be safely frozen and thawed once more.
What am I missing? I just can't make this (the phrase "If food is safe to eat, it's safe to refreeze") make sense in my head, but I know that it is me, not them, if you know what I mean.
