Description
Weighted sand compression removes moisture while infusing minerals.
Technical
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.
Culinary Significance
Creates crisp, dense textures with concentrated umami while avoiding brine dilution.
