In the Podcast, Kent Kirschenbaum, one of the founders of the group and a biochemist at NYU, talks some about the chemical creation of ice cream (specifically the Turkish Salepi Dondurma) and the use of Liquid Nitrogen. It's pretty cool, so I thought it was something everyone on this blog might be interested in. You can check it out here: http://www.nyas.org/snc/podcastdetail.asp?id=1832 Hi all,

It is a cool show and the ice cream is the best texture because of the low freezing point. We are serving a table side ice cream sundae made with LN.

It's a lot cheaper than through medical sources. The key to the whole thing is to whip the icecream pretty good before starting. The LN2 will put some nitrogen bubbles in there but you want to start with a frothy mix to begin with. It also freezes so fast you can dump in cookies or the like and they stay crunchy. Use a bread hook or something instead of a whisk in your mixer though if you add solids. You can also make dippin' dots style icecream with LN2. Make up a bach of ice cream recipie and put it through labware appropriate to slowly drip it into an LN2 bath. You'll get more or less perfect spheres of ice cream. Scoop them out into a cooler with dry ice to await serving. With this type of preperation though you want as little air as possible in the ice cream.
