Mix cornstarch and cold water in a small bowl until completely smooth. Set aside.
Add all sauce base ingredients to a saucepan. Whisk together before turning on heat.
Heat over medium, stirring frequently, until a gentle simmer forms at the edges — about 4–5 minutes.
Pour the slurry into the simmering sauce in a slow, thin stream while whisking constantly.
Whisk for 2–3 minutes until the sauce turns thick, golden, and glossy.
Taste and adjust — more honey for sweetness, more vinegar for tang, more soy sauce for depth.
Rest 3–5 minutes before tossing with wings or transferring to a jar.
