I wonder - could you do similar with crushed dry ice?  Sounds like a weekend project to me …..


Thanks for the recipe, David.  In the absence of LN2, that’d freeze up nicely in an ice cream freezer, too.

Hi Melissa,


I have made liquid nitrogen ice cream for years with no problems. Here is the link to my procedure


Remember, you are working with a cryogenic fluid.  Safety procedures must be followed as well a food safety procedures..


At the ACS meeting in Boston, the RSC hired the Wiches of Boston to make liquid nitrogen ice cream at their booth in the exposition. They used my recipe.
