Description
Partial gelatinization of wheat starch creates a translucent, elastic membrane.
Technical
Pouring boiling water (95-100°C) onto wheat starch initiates rapid gelatinization, where amylose molecules leach out and form helical structures that trap water, while residual amylopectin maintains structural integrity through hydrogen bonding.
Culinary Significance
Creates delicate wrappers for har gow (shrimp dumplings) that showcase fillings visually while providing a uniquely chewy-yet-tender mouthfeel.
