01 - In a mixing bowl, combine chicken with soy sauce, rice wine, egg white, and cornstarch. Blend thoroughly and allow to marinate for 15 minutes.
02 - Pour vegetable oil into a deep frying pan or wok and heat to 350°F. Dredge the marinated chicken pieces in cornstarch until entirely coated.
03 - Working in batches, deep-fry the chicken pieces until golden brown and crispy, approximately 4–5 minutes per batch. Transfer to a plate lined with paper towels to drain excess oil.
04 - Carefully pour off most of the oil, retaining 1 tablespoon in the pan. Add minced garlic, ginger, and chili. Sauté over medium-high heat until aromatic, about 30 seconds.
05 - In a clean bowl, whisk together fresh orange juice, soy sauce, sugar, rice vinegar, hoisin sauce, orange zest, and sesame oil. Reserve cornstarch slurry separately.
06 - Pour the sauce mixture into the pan with the aromatics. Bring to a simmer. Stir in the cornstarch slurry and continue cooking until the sauce thickens, 1–2 minutes.
07 - Return the fried chicken to the pan, tossing to coat evenly with the orange sauce.
08 - Transfer to a serving platter and garnish with sliced green onions and toasted sesame seeds. Serve immediately.
