Description
Cryogenic cooking preserves food texture and structure by rapidly freezing it using extremely low temperatures.
Technical
Cryogenic cooking involves submerging food in a bath of liquid nitrogen, reaching temperatures as low as -196°C, to prevent ice crystal formation and preserve texture. This technique can create unique textures and flavors by introducing air or gases into the frozen food. However, it requires specialized equipment and can be hazardous if not handled properly.
