I just made some instant ice cream for my lunch.
We had a load of unneeded dry ice from a delivery, and I had a pot of flavoured
skyr (Icelandic yoghurt-like stuff).
I smashed up the dry ice into a powder, by wrapping it in a tea towel and hitting it with a rubber mallet. Then poured the powder into a bowl of skyr and stirred it up. It froze quickly with lots of dramatic smoke and left some ice stuck to the bowl, so I lifted out the ball of 'ice cream' into another bowl to eat.
The end result was tasty, with a slightly acid flavour that I guess came from the CO2. Maybe I should have added some sugar first.
There's a few recipes on the web for doing the same with cream and milk, but yoghurt would probably work well.
