I know freezing is supposed to make foods expand but it seems that two pre-packaged sealed food items that I have in my freezer seem a bit puffy (chicken curry and chicken dumplings with cabbage) after taking them out of the freezer.
I don't think they were that way when I bought them but not sure. My freezer seems to working well (although my fridge is a bit variable) and foods always seem well-frozen. And I only left them out less than half an hour.
Can sealed food packages expand when they defrost rather than the other way around? Thanks!
