Can I Freeze An Unopened Carton Of Heavy Cream?
Decorating By projectqueen Updated 11 May 2007 , 7:57pm by tyty
I sometimes have trouble finding heavy cream at my grocery store and was wondering if I could buy an extra one and keep it in the freezer until I need it.
Has anyone tried this?
, Melissa I read somewhere that you can freeze heavy cream. mine is in the freezer right now.
I haven't tried it but I love Google and this is what I found. HIH!

I say it won't whip just because I would assume that it won't, but if it does, woohoo! Probably depends on fat percentage and how the freezing process takes place (all factors which would impact the fat emulsion and whether it's still functional upon thawing), and come to think of it, how the thawing took place (fridge vs. counter vs. microwave, etc). Probably similar-yet-different from the egg whites in cartons that won't whip properly because the pasteurizing denatures the protein.
mkolmar - I think everybody just says not to do it because you can't COUNT on it working, and it's way better safe than sorry! 
There may also be other considerations that I'm not aware of such as changes in the way it interacts with acids (maybe previously frozen cream is more prone to curdle?), etc., which would prompt your chefs to advise against freezing as a general matter.
bree--that's exactly what they told us--says freezing changes the structure of the product making untrustworthy. I guess if your doing for home use than no problem in trying. The Chefs run catering businesses, restaurants and teach us so they don't have time to play around. But if it works than why not try it?

Thanks for the link, I was going to ask about buttermilk. Most recipes call for 1 cup and most stores carry quarts. I always have leftovers and have to throw it away.
Buttermilk keeps indefinitely in my world, with no change in quality - seriously. This may be a rural legend (opposite of an urban legend?), but I've never heard differently.
I used the same half-gallon for six months (one...tablespoon... at...the....time). I may kill somebody one day, but everyone in my family does the same, and my great-grandmother is 95...
ETA - not for drinking purposes. Ewh. And I would certainly never make anything for anyone other than myself and immediate family with the elderly buttermilk.
