PRACTICAL WALKTHROUGH · PARAMETERS · COMMON MISTAKES
Rapid immersion of food in liquid nitrogen to instantly freeze it, preserving texture and nutrients.
Origin: Spanish molecular gastronomy chefs (1990s) — Spain
See full technique reference →The extreme temperature (-196 °C) of liquid nitrogen causes an immediate phase change of water in the food, forming ice crystals smaller than 10 µm. This suppresses ice‑crystal growth, minimizing cellular rupture, nutrient leaching, and flavor loss. The process is purely physical; only the water‑to‑ice transition occurs, though inert‑gas flushing can limit oxidation.
