Add beaten egg to the marinated chicken and mix to coat. Sprinkle 65 g cornstarch over chicken and stir until chicken is evenly coated with a slightly uneven layer, leaving some dry cornstarch.

Heat 3 tablespoons oil in a heavy skillet over high heat until nearly smoking. Add the coated chicken pieces in a single layer. Sear undisturbed for 2 to 3 minutes, or until the underside is golden. Flip and brown the opposite side, 2 to 3 minutes. Transfer chicken to a plate.

Remove skillet from heat for 2 to 3 minutes to cool slightly. Return to medium heat with 1–2 tablespoons oil remaining. Add dried chili peppers, minced garlic, and ginger. Stir-fry until fragrant.
