01 - Combine chicken, soy sauce, rice wine, egg white, and cornstarch in a mixing bowl. Mix until the chicken is evenly coated. Allow to marinate for 15 minutes in the refrigerator.
02 - Heat vegetable oil in a deep frying pan or wok to 350°F (180°C). Dredge marinated chicken pieces in cornstarch until thoroughly coated.
03 - Fry chicken in batches, turning as needed, until golden brown and crispy, approximately 4–5 minutes per batch. Transfer fried chicken to a plate lined with paper towels to drain excess oil.
04 - Pour off most of the oil from the wok, reserving about 1 tablespoon. Add garlic, ginger, and chili; sauté over medium heat until aromatic, about 30 seconds.
05 - In a separate bowl, combine orange juice, soy sauce, sugar, rice vinegar, hoisin sauce, orange zest, and sesame oil. Exclude cornstarch slurry at this stage.
06 - Pour prepared sauce mixture into the wok with the aromatics and bring to a gentle simmer. Stir in cornstarch slurry and continue cooking until sauce thickens, about 1–2 minutes.
07 - Add fried chicken to the wok and toss to evenly coat with the orange sauce.
08 - Serve immediately, garnished with green onions and toasted sesame seeds.
