What You Need to Know
Nitrogen infusion is a modernist technique that utilizes the rapid cooling properties of liquid nitrogen to freeze food, preventing the growth of bacteria and other microorganisms, and creating unique textures and flavors. The process involves the use of cryogenic freezing, which preserves food by rapidly lowering its temperature to around -196°C (-320°F).
