How to Salt-Roasting

What You Need to Know

Salt-roasting relies on the high thermal conductivity of sodium chloride (NaCl) to transfer heat uniformly. The salt crust forms an insulating layer that reduces moisture evaporation via vapor pressure equilibrium. In some preparations, egg whites are mixed with salt to create a hardened crust (salt-crust baking).

Used for delicate proteins like fish and poultry where moisture retention is critical. Creates a dramatic presentation when cracked open tableside. The technique naturally seasons food while preventing direct salt penetration into the flesh when properly executed.
