The balls of ice cream that smoke are known as "smoking ice cream" or "smoke-filled ice cream." These unique ice cream creations are made using liquid nitrogen. Liquid nitrogen has an extremely low temperature (-196 degrees Celsius or -321 degrees Fahrenheit) and when it comes into contact with the ice cream mixture, it rapidly freezes it, creating a dramatic cloud of vapor or smoke.
To make smoking ice cream, the ice cream base is typically prepared in advance, and then liquid nitrogen is added to the mixture while it is being churned or poured in proper ice cream paper cups. The extreme cold of the liquid nitrogen causes the ice cream to freeze almost instantly, resulting in a smooth and creamy texture. The vapor or smoke that is produced is a result of the liquid nitrogen rapidly evaporating when it comes into contact with the warmer air.
The visual effect of the smoking ice cream adds an element of fun and novelty to the dessert experience. However, it's important to note that liquid nitrogen should be handled with caution and only used by professionals who are trained in its safe handling and usage.
