I read somewhere a while back that just about anything is freezable, so since milk was on a really good sale price recently, I purchased a lot and froze it. Sure enough, when it thawed out, it was just as good as new! Then I froze canned biscuits and rolls, fully expecting them to ruin, but they worked just fine, too! Next, I tried heavy cream and sour cream. DON'T DO THIS! Neither was the same consistency after being thawed out. We're still using the sour cream and it's edible, but more like soup than cream. Live and learn!
