One of the neatest bits of my first trip to Denmark wasn’t Legoland amazingly enough. It was a place that did liquid nitrogen ice cream.
Istid is this little shop on a residential street in Copenhagen. Happily the street I was staying with a friend on! The setup is simple: on a counter behind glass are four brightly coloured Kitchen-Aid mixers; opposite them is a chalkboard explaining the four flavours of ice cream with toppings they offer.
When you pick your flavour and size they go to the matching mixer, pour the pre-mixed ice cream ingredients into it, start the mixer and then pour in the liquid nitrogen. Instantly the mixer seems to transform into a witches cauldron with fog spilling over the edge. As the fog clears, the liquid they poured from the caraffe has transformed into ice cream - magic!
And it tastes delicious. Apparently this is due to the rapid cooling by the liquid nitrogen causing smaller ice crystals and therefore creamier ice cream. Or it’s caused my magic.
