Mix the marinade ingredients (light soy sauce, dry sherry, 3 drops sesame oil, flour, 2 tablespoons cornstarch, 2 tablespoons water, baking powder, baking soda and vegetable oil)
Soak chicken pieces in the marinade for 30 minutes.
To prepare the sauce, place 1/2 cup water, chicken broth, white vinegar, 1/4 cup cornstarch, sugar, dark soy sauce, 2 tablespoons sesame oil, chili paste and garlic in a small pot
and bring to a boil, stirring continuously.
Turn the heat down
to low and keep warm while you are deep-frying the chicken.
Heat peanut oil in a deep skillet over a medium-high heat.
Add the marinated chicken pieces a few at a time, and deep-fry
until golden brown (about 4-6 minutes).
Drain chicken pieces on paper towels and then repeat the process with the rest of the chicken pieces.
Just before you are finished deep-frying, bring the sauce back up to a boil.
Place the chicken on a large platter and pour the sauce over it.
