This was inspired by another poster saying that they did not like wasting space in the freezer for an ice cream maker, since it is a unitasker.
I have used the freezing bowl for a number of things...
1) At a BBQ keep ice in it for drinks.
2) In a cool box - just to keep it cool
3) Put a tea towel 'over' it and used it as a wine chiller.
4) Used it to quickly chill liquor / cocktails
So it is not a unitasker for me. Are there other devices which you use in odd ways? Like using a corkscrew to get the meat out of crab legs. (I just invented that one, but I'm sure someone has done it.)
