Description
A multi-stage duck preparation creating ultra-crisp skin through controlled dehydration and sugar polymerization.
Technical
Involves subcutaneous air pumping to separate skin from fat, maltose syrup glaze formation (C12H22O11), and convection roasting that creates a sugar glass matrix through caramelization (C6H12O6 → C6H6O3 + 3H2O) while rendering fat via thermal conduction.
Culinary Significance
Produces the iconic 'crisp-shattering' texture contrast against moist meat, requiring precise humidity control during drying.
