Ingredients needed to make simple Vanilla Liquid Nitrogen Ice Cream:
Milk
Heavy Cream (Half and Half will do nicely)
Real Vanilla (not that fake junk that's sold!)
Sugar
Liquid Nitrogen
Equipment needed:
Stainless Steel mixing bowl
Wooden mixing spoon
Gloves
A big sink or a level place out side
Directions:
First figure out how much you want to make. Multiply the total amount of ice cream by five to get the amount of Liquid Nitrogen needed to freeze the ice cream. A gallon of ice cream will thus need five gallons of Liquid Nitrogen.
Mix the Milk, Cream, Vanilla and sugar in the mixing bowl. The ratios should be twice as much cream as milk and about 8 tbsp of vanilla for every gallon of liquid. Sugar should be about 1 cup dry measure per gallon. If that's too sweet then half it. I do not know how artificial sweeteners react to the cold, so I don't recommend the usage of them.
Mix the ingredients until the sugar has dissolved into the milk and cream. Add in any fixings (candy, coffee, other flavors). Move to the sink if you haven't already.
Pour in the Liquid Nitrogen slowly and mix with the wooden spoon until completely frozen, which should be about 10 minutes. Wear the gloves, because it's going to be cold.
For a better freeze, prepare the icecream in a pressure cooker, and after adding the Liquid Nitrogen, clamp shut for 5 minutes.
Eat!
