Making Ice Cream With Liquid Nitrogen

Posted by timothy on from the something-for-the-nothern-hemisphere dept.

JasonMaggini writes "Popular Science has an article on how to whip up a batch of ice cream in 30 seconds or so by using liquid nitrogen. Just the thing for those hot summer days. The article is by Theodore Gray, creator of the ultra-spiffy Periodic Table Table."

    This is the exact process that Dippin' Dotsuses to make ice cream in little tiny spheres (about 2-5 mm across).

    The process was determined around 1988 by Curt Jones (a biologist interested in cryogenics...the science of freezing...not cryonics, the science of "Disney on Ice"). He started his company and now you can get Dippin' Dots everywhere from malls to theme parks.

    You might even be able to catch a rerun of the FoodTV show, Unwrapped, where they discuss the manufacturing process. It's show #CWSP11 and it'll air again at these times.

    PS - Yes, I know Walt Disney isn't actually frozen....but Teddy Ballgame is.

    This is silly, and not true, since there was no concept of a "teabag" in Eastern Europe.
    People made tea from tea essense.

    What people did do is to put a lump of sugar into their mouth as they were drinking the tea -- instead of putting it into the tea.
    This was more of a matter of personal preference than desire to save sugar (although there was a little bit of both -- sugar was often given out via ration cards)
