I once placed a can of beer in the freezer for an hour. It did not freeze, and it was great.
However, now I need to cool some whipped cream (un-whipped), and the packet says I need to keep it in the fridge for 24h. But I don't have that long; and I'm worried that keeping it for 1h might be too long.
Is there a rule of thumb (perhaps in relation to weight), or do you have experience with how long I should keep this in the freezer?
