Whisk honey, soy sauce, 2 tablespoons water, sesame oil, vinegar, and red pepper flakes in a bowl. Set aside the sweet sauce mix.
Mix cornstarch and 1 tablespoon water in a small bowl to make a slurry. Set that aside too.
In a shallow dish, combo flour with chili powder, cumin, coriander, and onion powder. Coat chicken pieces well then shake off excess flour.
Heat a couple inches of oil in a skillet over medium-high heat till it shimmers. Fry the chicken in batches about 3 to 4 minutes each side till golden brown and crispy. Lay them on paper towels to drain fat.
Drain most oil from skillet but keep a bit. Pour in your honey sauce and bring it to a simmer while stirring.
Add the cornstarch slurry gradually and stir until the sauce thickens up nicely about 1 to 2 minutes.
Throw the crispy chicken back in skillet and toss to coat every piece in that sweet, sticky glaze.
Serve hot with optional garnish of sesame seeds and green onions for the full experience.
Notes
Serve with rice or steamed vegetables. Garnish with sesame seeds or green onions if desired.
