These appliances employ a frozen metal surface chilled to sub-zero temperatures to create a unique dessert. A liquid ice cream base is poured onto this cold surface and rapidly manipulated with spatulas. As the base freezes, it is spread thinly and then scraped into aesthetically pleasing rolls. This process allows for the incorporation of various mix-ins, like fruits, candies, and cookies, directly into the ice cream.
The novelty of the preparation and the customizable nature of the final product have contributed to a surge in popularity. This method offers a theatrical experience for customers, transforming ice cream creation into an engaging spectacle. The rapid freezing process creates a distinctively smooth and dense texture, differing from traditionally churned ice cream. Furthermore, the adaptability of the process allows businesses to offer an extensive menu of flavor combinations, catering to diverse palates and dietary preferences.
