Title: Liquid Nitrogen Ice Cream
Source: http://chemistry.about.com/od/demonstrationsexperiments/ht/n2icecream.htm
Target Age: PK - 12th grade
Materials Required:
5 or more liters of liquid nitrogen
gloves and goggles recommended
large plastic or stainless steel punch bowl or salad bowl
4 cups heavy cream (whipping cream)
1-1/2 cups half-and-half
1-3/4 cups sugar
1 quart mashed fresh strawberries or thawed frozen berries
additional half cup of sugar if you are using unsweetened berries
wooden spoon
wire whisk
Prep Time Required: 15 Min
Demo Time Required: 5 Min (pouring in liquid nitrogen and stirring)
Description:
This recipe makes a half gallon of strawberry ice cream. First, mix the cream, half-and-half, and sugar in the bowl using the wire whisk. Continue mixing until the sugar has dissolved.
If you are making vanilla or chocolate ice cream, whisk in vanilla or chocolate syrup now. Add any other liquid flavorings you might want.
Put on your gloves and goggles. Pour a small amount of liquid nitrogen directly into the bowl with the ice cream ingredients. Continue to stir the ice cream, while slowly adding more liquid nitrogen. As soon as the cream base starts to thicken, add the mashed strawberries. Stir vigorously.
When the ice cream becomes too thick for the whisk, switch to the wooden spoon. As it hardens more, remove the spoon and just pour the remaining liquid nitrogen onto the ice cream to fully harden it.
Allow the excess liquid nitrogen to boil off before serving the ice cream.
