If you want to try it yourself and don't have a nitrogen cooling system handy, Modernist Cuisine suggests a block of dry ice under a baking steel that's been in the freezer.
Get fancy by shaving the ice cream into rolls. To make ice-cream rolls, use a chilled, homemade ice-cream base, or melt down some store-bought ice cream. Some bases, such as sorbets, can freeze up too hard, too quickly. In these cases, add a ripe banana. The banana softens the frozen product and creates a pliable texture ideal for curling. In fact, in the recipe below, we've made curls using just frozen banana and kiwi. Experiment with other fruits that are naturally creamy, such as persimmon, cherimoya, and avocado.
