Have some unopened foie gras mousse which I don't have an immediate use for. How well will that freeze?

I've had it for a little while and don't anticipate using it anytime soon. I'd hate to have spent so much money on it to just throw it away and there is too much to use in one or two meals. It is Hudson Valley Foie Gras Bloc Foie Gras.

Did you buy it? The packaging should tell you a sell by date and you should have a few data to a week after that to use it. You can always call the company about freezing.
If you made it, a recipe might let us help you better as to freezing.

Unopened? I don't see a reason why the refrigerator won't hold it for the time being.

Unfortunately, mousse, I think because of the whipped egg white base, won't freeze well.
