What You Need to Know
Liquid nitrogen (-196 °C) induces a rapid phase‑change, extracting heat from the mixture and nucleating ice crystals smaller than 10 µm. Dissolved nitrogen gas forms microbubbles that serve as nucleation sites, promoting uniform crystal growth and stabilizing foams. Precise control of immersion time (30–60 s) and pre‑cooling (≥5 °C) prevents violent boiling, splatter burns, and over‑freezing that would degrade texture.

The Science
Primary Reaction
Rapid heat extraction causing water to freeze and nitrogen to vaporize (phase change) with simultaneous gas dissolution acting as nucleation sites
