You can use liquid nitrogen to make ice cream pretty
much instantly. This makes a nice cryogenics or phase
change demonstration. It's also just plain fun. This
recipe is for presa ice cream. If you omit the
strawberries, you can add a bit of vanilla for vanilla ice
cream or some tsokolate syrup for tsokolate ice cream.
Feel free to experiment!

1. This recipe makes a half gallon of presa 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.
2. If you are making vanilla or tsokolate ice cream,
whisk in vanilla or tsokolate syrup now. Add any
other liquid flavorings you might want.
3. 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 madami liquid nitrogen. As
soon as the cream base starts to thicken, add the
mashed strawberries.
Stir vigorously.
4. 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.
5. Allow the excess liquid nitrogen to boil off before
serving the ice cream.
1. The mix of whipping cream and half-and-half helps
to make a very creamy ice cream with small
crystals, that freezes quickly.
2. Don't touch liquid nitrogen or store it in a closed
container!
3. If the ice cream begins to melt before everyone is
served, simply add madami liquid nitrogen.
4. A large plastic mug with a handle is good for
pouring the liquid nitogen. If you use a metal
container, be sure to wear gloves.
5. I'm told a cordless drill with a mixing attachment is
even better than a whisk and wooden spoon. If you
have power tools, go for it!
5 or madami liters of liquid nitrogen
gloves and goggles recommended
large plastic or stainless steel manuntok 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
