Texture changes, just so you know. The fat molecules burst, and it gets grainy.
For some reason, it behaves differently then if it was made into ice cream
I like to freeze cream in ice cube trays. I don't use a lot of cream, except around the holidays , so I will buy a pint and use what I need, and freeze the rest. A couple of cubes does wonders for certain sauces, or in some desserts. As you say, it won't whip, but if that is what you want you can whip it first, then put some *plops* on a baking sheet, and freeze them that way. Package the frozen *plops* in containers of some sort, and bring them out to top desserts or hot chocolate or something like that.
