Description
Cryogenic smoking infuses flavor into foods by freezing them at liquid‑nitrogen temperatures and then smoking at sub‑freezing temperatures, preserving texture and moisture.
Technical
The technique relies on rapid freezing to lock in moisture and prevent ice‑crystal damage, followed by exposure to smoke at -10 °C to 0 °C. Phenolic and aldehydic compounds from the smoke penetrate the frozen matrix without significant thermal degradation, allowing for a delicate smoky aroma while maintaining protein integrity.
