Liquid Nitrogen Ice Cream

My Aunt and Uncle are the King and Queen of making liquid nitrogen ice cream, seriously. They have the process down!  And since my uncle has a chemical engineering background, he explains each step of the process as he goes- feels like you’re on an episode of Bill Nye the Science Guy a bit (it’s pretty cool)!  I always have thought it sounds kind of scary to make, like you need a degree in Bio-Chem or something.  And I am not going to lie, it is dangerous- safety goggles and closed toed shoes are definitely a good idea.  After watching each step, though, I want to give it a try sometime!  For those of you who want to try it, here are the directions.

Here is my Aunt Renee’s recipe: (and I got the directions from here.)

1 1/2 quarts Half&Half

1 quart Heavy Cream

1 1/2 cup Sugar

5 tablespoons Vanilla

  • In the large steel bowl, mix half&half and cream.
  • Add the vanilla and sugar. Stir until the sugar dissolves.
  • Now, you can add any other ingredient you want- fruit would be good, chocolate chips, nuts… Be creative!
  • Next, put on your safety glasses and gloves.  You might want to put the bowl in your sink just in case it overflows (which it probably will) or spread out some plastic on the table. It’s impossible to measure how much liquid nitrogen to add, so just pour about a quart  of liquid nitrogen into the bowl.
  • DO NOT STIR THE MIXTURE… just yet. Let the liquid nitrogen do its job of partially freezing the mixture. If you stir too soon, the concoction will bubble over and you’ll have a mess (and you’ll waste some of your ice cream).
  • Stir the mixture with the wooden spoon. Some of the cream will be completely frozen while other parts will still be liquid. Keep stirring until you have a consistent mixture, and then add more liquid nitrogen.
  • Let it freeze for a few seconds before stirring.
  • Stir, stir, and stir some more until you have a consistent mixture.
  • Keep adding small amounts of liquid nitrogen until you have the perfect creamy consistency.
