Ok I learned the hard way if the carton says ... DO NOT FREEZE then I guess that means DO NOT FREEZE. Recently, I purchased a moderate amount of Heavy Whipping Cream. It didn't get used as quickly as I planned so I thought I would freeze it and then be able to use it when needed. WRONG! Who would have guessed? What a shame to waste such a delightful and extremely useful product ... not to mention expensive. So take it from me ... READ THE LABELS! ~ Chef Wilkinson ~
