What You Need to Know
Utilizes alkaline egg whites (pH ~9) to disrupt myofibrillar proteins while cornstarch forms a protective colloid, preventing excessive protein coagulation during high-heat cooking. The combination creates a velvety mouthfeel through partial protein denaturation and moisture retention.
Essential for authentic stir-fry textures in Chinese cuisine, producing the characteristic 'slippery' yet tender bite in dishes like beef with broccoli or kung pao chicken.
