To a large bowl, add cornstarch, water, flour, soy sauce, egg white, and white pepper. Stir until well combined. Add chicken and toss to coat thoroughly.
To a large pot over medium heat, add 3-4 inches vegetable oil. Heat the oil to 340°F.*
When the oil has reached 340°F, carefully lower the chicken pieces into the hot oil. Depending on the size of your pot, you may have to work in batches. Cook for about 5-7 minutes, or until golden brown.
Using a slotted spoon, remove the chicken from the oil and place onto a paper towel-lined baking sheet. Before frying the next batch, check that the oil temperature is at 340°F.
Once all the chicken has been fried, heat the oil to 375°F. Fry the chicken pieces a second time for 30-60 seconds, or until extra crispy. Set aside to cool on a wire rack.
To a large skillet over medium heat, add honey, soy sauce, ketchup, brown sugar, sesame oil, rice vinegar, Shaoxing wine, and minced garlic. Mix to combine. Bring the sauce to a simmer and cook for 1-2 minutes, or until the sugar has dissolved.
Add the fried chicken to the sauce, tossing to coat evenly.
Sprinkle sesame seeds over the chicken and garnish with chopped green onions. Serve.
