Or instead of spending $35k on this machine, attach a beater to a power drill, pour the ingredients into a large bowl, mix while pouring in the LN2 (it helps to have one person holding the bowl and mixing while a second person pours), and serve when ready. Just be prepared to clean up milk splatters from the work area.

Or, instead of playing around with Liquid Nitrogen, which is dangerous, expensive and hard to find, you could use any of the far cheaper and commonly available ice cream makers that have been on the market for decades.

Not to mention whether freezing ice cream that fast would even taste good or not.

There's a company in Minnesota named Blue Sky Creamery which uses liquid nitrogen to make ice cream. It's pretty good stuff -- the extremely fast freezing process makes the ice cream very dense with smaller ice crystals than you get in other ice creams.

Fortunately, I can just buy their stuff at the grocery store a few miles from my house -- a lot cheaper than $35k :-p

Dustman.... Seriously?

LN freezes it extremely quick, not affecting flavor in a negative way, and thus makes the ice crystal extremely small, as Mulad said. The end result is a smooth and creamy texture and a crisp, fresh taste.

With such low temperatures you can even use a higher percentage of cream which allows for an even richer and creamier ice cream.

World gone mad! Whatever happened to that singular pleasure of cranking the ice cream until your arm almost fell off (all the while anticipating the pleasure to come)

This reminds me of the H-Chocolate from a few years back. A nifty counter-top appliance used in making hot chocolate. But yeah, poor sales due to the inconvenience of acquiring hydrogen. Oh, and it was volatile.

Liquid nitrogen? Please, I don't have that kind of time on my hands. Let me know when the liquid helium model is available then I will drop my $35k. I want my icecream to be as close to absolute zero as possible.

I'm more aligned in thinking with Kim. My first participation with home-made icecream was to sit on the freezer to hold it while my Dad or one of my older brothers finished the cranking. Then, I finally got the honor of cranking while my younger brother sat on the freezer. Wasn't too long after my promotion to the cranking status that I helped invest in a new White Mountain freezer with a MOTOR!
But, nitrogen? And, Helium?! Whoa, dude. What would happen to my tongue when I lick the beater?

If you get the new ARC $25k interest free loan from the SBA-- this looks like a great way to spend it all!
