Thanks.  I'm not sure that in a year I'd use that much but possible.  The other problem I would have is the high sodium content of most freeze dried foods - which is why dehydrating my own cooking is probably a better choice - even if it weighs a little more.

I agree that the taste has become pretty good - everybody's stroganoff seemingly very good.  But then I wonder if you got some powdered sour cream if all meals wouldn't benefit.
