Liquid Nitrogen Ice Cream!

Being a chemistry geek doesn't mean you can't have fun!

Step 1: Gather Ingredients

Gather ingredients and necessary tools:
4 cups whole milk
2 cups heavy whipping cream
1 tsp vanilla
1 1/2 - 1 3/4 cup sugar
1-2 liter Liquid Nitrogen  (CAUTION!!!!!  Careful handling must be used to avoid burns)

Metal bowl
Metal mixing spoon
Bowls and spoons

Step 2: Add Ingredients to Metal Bowl

Add all ingredients, excluding the liquid nitrogen, into a large metal bowl

Step 3: Add Any Desired Mix-ins

Add desired mix-ins to the bowl.  These can include candy bars, fruit, jam, chocolate syrup etc.

Step 4: Mix Ingredients in Bowl

Mix all the ingredients in the bowl until the sugar has dissolved completely.

Step 5: Add Liquid Nitrogen

Pour the liquid nitrogen slowly into the bowl while mixing.  Add in intervals to avoid spillage and to make sure the mixture is completely frozen

Step 6: Mix Vigorously With Metal Spoon

Mix the ice cream vigorously with a metal spoon.  This will smooth out the ice cream into an edible and recognizable substance.

Step 7: Serve and Enjoy!

Serve and enjoy the finished product.  If no steam emits, all liquid nitrogen has dissipated and it is safe to eat.

That's really dangerous

Have you tried this with liquid helium? I've been trying to find out if anyone has done this and haven't found an answer yet. Is it even creamier because of the tinier crystal formation? Does it make your voice get higher when you eat the ice cream because there is helium in it? etc...

I haven't tried it with liquid helium. It should be smoother with smaller crystal formation because it cools faster. However, I doubt it would raise your voice. The liquid nitrogen is only used to cool the mixture, it does not bond with the mixture or change the chemistry. Liquid helium would do the same thing. It would cool the ice cream quicker but would not actually have helium in it unless you ate it while it was still steaming...
