01 - Combine chicken pieces with soy sauce, rice wine, egg white, and cornstarch in a bowl. Mix thoroughly until chicken is evenly coated. Let marinate for 15 minutes at room temperature.
02 - Pour vegetable oil into a deep pan or wok. Heat to 350°F over medium-high heat.
03 - Remove chicken from marinade. Dredge each piece in additional cornstarch, pressing gently to ensure an even coating. Shake off excess powder.
04 - Fry chicken in batches for 4-5 minutes until golden brown and crispy. Use tongs to turn pieces halfway through. Transfer to paper towels to drain excess oil.
05 - Drain oil from pan, leaving 1 tablespoon. Return pan to medium heat. Add garlic, ginger, and sliced chili. Sauté for 30 seconds until fragrant, being careful not to burn.
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. Bring to a gentle simmer.
07 - Stir in 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 sauce. Toss gently until all pieces are evenly coated. Transfer to serving platter. Garnish with sliced green onions and toasted sesame seeds. Serve immediately.
