Velvet the Chicken
In a medium bowl, combine the diced chicken with the light soy sauce, Shaoxing wine, cornstarch, and baking soda. Mix thoroughly with your hands until the liquid is fully absorbed.
Velveting creates a protective barrier around the meat, trapping juices inside and ensuring the chicken remains velvety soft under fierce wok heat.
The liquid should completely disappear, leaving a thin, glossy film over the chicken pieces.
