Description
Primitive but effective moisture removal through conductive heat transfer from heated sand particles.
Technical
Utilizes sand's high thermal mass and low specific heat to slowly dehydrate tissues through conduction rather than air convection. Sodium-rich desert sands may impart mineral preservation effects.
Culinary Significance
Creates intensely concentrated flavors while preventing microbial growth through low water activity (aw < 0.6).
