A flat, extremely cold metal surface is used to create this frozen dessert. Liquid ice cream base is poured onto the surface, where it freezes almost instantly. The thin layer of frozen dessert is then scraped into rolls using specialized spatulas. Various toppings, such as fruit, candy, and sauces, can be mixed into the base before freezing, allowing for customized flavor combinations.
This method of preparation offers several advantages. It allows for rapid, on-demand dessert creation, ideal for catering events and busy restaurants. The process is also visually engaging, adding an element of entertainment to the dining experience. Furthermore, the rapid freezing minimizes ice crystal formation, resulting in a smoother, denser texture compared to some traditionally churned ice creams. While a relatively recent trend in some regions, the technique has roots in Southeast Asian street food, gaining global popularity through social media and its unique customizable nature.
