Foamification using siphons and foamers creates airy textures by dissolving nitrous oxide in cold liquids and releasing it to form microbubbles.
Origin: French molecular gastronomy chefs (1990s) — France
See full technique reference →Nitrous oxide dissolves in the liquid at low temperatures and high pressure, forming a supersaturated solution. Upon pressure release, the gas expands, creating microbubbles that are stabilized by surfactant films. The resulting foam is a colloidal dispersion of gas in liquid, with stability governed by surface tension and viscosity.
Primary Reaction
Dissolution of N₂O in liquid followed by rapid expansion upon pressure release
