Last Sunday, Dean O’Hara held her Liquid Nitrogen Workshop at our dorm and showed us how to make ice cream with it. Liquid nitrogen exists at a very low temperature and has to be stored in a vacuum flask. Once liquid nitrogen is exposed to the air, it boils away. (Dean O’Hara poured the liquid nitrogen from the bowl onto the floor to demonstrate how fast it evaporates.) The vapor that you see is actually water vapor. The liquid nitrogen is useful for cooling things, especially ice cream mixtures. It’s also useful for freezing fruit and then smashing it onto the ground.

I am interested in molecular gastronomy, so I was excited to see a liquid nitrogen ice cream demonstration in real life… finally! I then found out that Amherst’s science library has the whole collection of Modernist Cuisine– pinch me now.

One volunteer pours the liquid nitrogen and the other stirs the ice cream mixture. No one got any cold burns from accidentally touching the liquid nitrogen. The photo below is the result of the first batch.
