Am I last person to know about this? People are out there making ice cream right in front of your eyes with liquid nitrogen.
When we were in California, our friend took us to the cutest little ice cream parlor, à la minute. They take the ingredients and mix it with liquid nitrogen in a Kitchen Aid mixer and in just a couple minutes you have a creamy little treat in your hands. Apparently, the use of the nitrogen helps to freeze everything faster so you can prevent ice crystals from forming, thus making a creamier, smoother ice cream. I am no scientist, but I do know that this was killer. I loved it and can't wait to go back when we're down there next. There were so many great flavors to try--we went with vanilla bean and olive oil.
