Check out the pictures from Ices Plain & Fancy where they revived a technique for making the freshest ice cream possible by mixing the ingredients right before your eyes and then quickly freezing it with Liquid Nitrogen *** minus 321 degress *** blow torches are then used to warm it up for serving!
The whole process is a show in itself and the end results are incredible! Check it out sometime just to the south & east in the Shaw Neighborhood - 2256 S 39th Street at Shenandoah: http://www.icesplainandfancy.com/
