Description
Friction-induced cell rupture releases capsaicinoids and alliinase enzymes.
Technical
Stone grinding ruptures chili parenchyma cells, freeing capsaicin (C18H27NO3) while simultaneously crushing garlic to initiate alliin-to-allicin conversion (C6H10OS2). Shear forces emulsify oils with minimal heat degradation.
Culinary Significance
Superior flavor integration vs. blade chopping, with stone particles creating micro-abrasions that increase surface area for spice bloom during cooking.
