Description
Moist-heat braising that achieves protein denaturation while infusing savory-sweet flavors through osmotic exchange.
Technical
The sealed environment creates a hydrothermal system where collagen converts to gelatin at 60-70°C while preventing myofibrillar protein shrinkage. Soy sauce's sodium chloride (3-5% brine concentration) facilitates partial hydrolysis of muscle fibers.
Culinary Significance
Simultaneously tenderizes tough cuts while building layered umami through gradual liquid reduction and starch-thickened sauce consistency.
