For the Chicken
Cut chicken into thin pieces. Season with soy sauce, garlic and ginger, white pepper, 1 egg, flour and corn starch. Mix until the chicken pieces are coated. It'll be a thick batter consistency. Add more flour and cornstarch if needed.
In a cast iron skillet heat up oil over medium heat.
When the oil is hot, fry the chicken in batches over medium heat for 4-5 minutes. Work in batches to not overcrowd the pan. Remove from the oil then turn up the heat to medium high and double fry until the chicken gets crispy and you desired color. Drain on a wired rack.
Drain the oil and leave about 1 tbsp. Add in ginger and garlic on medium heat and sautè until fragrant. Add in Shaoxing wine to deglaze the pan then pour in the sauce and corn starch slurry over medium heat. Allow the sauce to simmer. Once the sauce thickens, add in the chicken and toss until the chicken is fully coated.
Remove from the heat. Top with sesame seeds and green onions.
