In a bowl, whisk together egg whites, cornstarch, and a pinch of salt until silky and slightly frothy. Add the chicken pieces and toss to coat completely. Let them rest for about 10–15 minutes so the velveting helps lock in moisture.
Pour oil into your skillet or wok so it’s about an inch deep and heat it over medium‑high. You want it hot enough that a drop of batter sizzles instantly — that’s the key to a crispy exterior.
Carefully place the marinated chicken into the hot oil in batches. Avoid overcrowding so each piece gets golden and crisp. Fry for about 3–4 minutes per batch until beautifully golden, then remove and drain on paper towels or a rack.
In a small saucepan, combine honey, minced garlic, soy sauce, and black pepper over medium heat. Stir and let it come to a gentle boil — after a minute or two it should thicken with a glossy sheen.
Add the fried chicken pieces to the simmering sauce and gently toss until every bite is coated in that sticky, sweet sauce. Sprinkle with sesame seeds and sliced green onion for a final flavor boost and beautiful presentation.
