The Best Way to Freeze Cream
Instead of letting any bit of a carton of heavy cream spoil in your refrigerator, turn to your freezer instead. It is possible to freeze heavy cream—here's the best way to do it.
Instead of letting any bit of a carton of heavy cream spoil in my refrigerator, pour the extra into an ice cube tray and freeze. Once the cubes are frozen, pop them out of the tray, and place them in a plastic bag. Each ice cube weighs about 1 ounce, or equals about 2 tablespoons. This way you'll reduce waste and always have a bit of cream handy.
If you have a large amount of leftover cream, simply freeze it in the carton that it came in. If the carton is completely full and unopened, you need to pour off a few tablespoons to allow room for expansion during freezing.
