What You Need to Know
Physical pressure ruptures cell walls via plasmolysis, concentrating flavors through osmotic dehydration. Sand's mineral content (silica, trace elements) may catalyze enzymatic breakdown of pectins.
Creates crisp, dense textures with concentrated umami while avoiding brine dilution.
