01 - Combine chicken with soy sauce, rice wine, egg white, and cornstarch in a bowl. Mix thoroughly to coat each piece. Let marinate for 15 minutes at room temperature.
02 - Heat vegetable oil in a deep pan or wok to 350°F. Maintain temperature throughout frying for optimal crispiness.
03 - Dredge marinated chicken pieces in additional cornstarch until thoroughly coated. Shake off excess powder before frying.
04 - Deep-fry chicken in batches, being careful not to overcrowd the pan. Cook for 4-5 minutes per batch until golden brown and crispy. Remove and drain on paper towels.
05 - Discard most of the oil, leaving 1 tablespoon in the pan. Add garlic, ginger, and sliced chili. Sauté until fragrant, about 30 seconds.
06 - Mix orange juice, soy sauce, sugar, rice vinegar, hoisin sauce, orange zest, and sesame oil in a bowl. Pour mixture into the pan and bring to a simmer.
07 - Stir in cornstarch slurry and cook for 1-2 minutes until sauce thickens and coats the back of a spoon.
08 - Add fried chicken to the sauce, tossing quickly to coat evenly. Serve immediately garnished with green onions and sesame seeds.
