Description
Moist-heat gelatinization of nixtamalized corn dough within plant wrappers creates cohesive texture while infusing aromatic compounds.
Technical
Steam-mediated starch gelatinization (60-80°C) in alkaline-treated maize dough (masa), with simultaneous transfer of volatile organic compounds from corn husks/banana leaves via moist heat convection.
Culinary Significance
Essential for achieving tamal's characteristic tender-but-cohesive texture while preventing dough drying; husk/leaf wrapping imparts vegetal aromas.
