01 - Combine chicken pieces with soy sauce, rice wine, egg white, and cornstarch in a bowl. Mix thoroughly until each piece is coated. 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 - Remove chicken from marinade and dredge each piece in additional cornstarch, pressing gently to ensure even coating. Shake off excess powder.
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. Transfer to paper towels to drain excess oil.
05 - Discard most of the frying oil, leaving 1 tablespoon in the pan. Add minced garlic, ginger, and sliced chili. Sauté for 30 seconds until fragrant, being careful not to burn the garlic.
06 - Whisk together orange juice, soy sauce, sugar, rice vinegar, hoisin sauce, and orange zest in a bowl. Pour mixture into the pan with aromatics and bring to a gentle simmer.
07 - Stir in the cornstarch slurry while constantly mixing. Continue cooking for 1-2 minutes until sauce reaches desired consistency. Remove from heat and stir in sesame oil.
08 - Add fried chicken to the saucepan. Toss gently until all pieces are evenly coated with the orange glaze. Transfer to serving platter and garnish with sliced green onions and toasted sesame seeds. Serve immediately while hot.
