What You Need to Know
The extreme cold of liquid nitrogen (-196 °C) induces rapid nucleation of water and fat, producing ice crystals smaller than 20 µm. This suppresses sugar crystallization and preserves volatile aromatics, resulting in a smooth, creamy mouthfeel. The process exemplifies modernist culinary techniques that harness cryogenic temperatures for sensory enhancement.
