I found a recipe for a liquid nitrogen cocktail
http://chef-a-gogo.com/tag/liquid-nitrogen-cocktail/
The ingredient list is:
Liquid nitrogen martini ingredients
5 ml lychee liqueur (Use Suntory Mango liqueur if available)
50ml Absolut Mango vodka
30g very ripe mango cubes (in season)
25ml liquid nitrogen
20ml pineapple juice, freshly squeezed
5ml lime juice, freshly squeezed
The guys website is clearly that of a foodie, or atleast someone who likes different drinks. But the entire lack of understanding of this stuff is worrying. Yes it is a very good way to cool the drink down without changing the composition, but he also says to serve it quickly whilst it is still "smoking". er, excuse me?! That means that it has not all evaporated. (I got my units wrong earlier. 25ml of liquid nitrogen is just under 24l when vaoprised, done the calcs more accurately this time.)
