Add the orange juice, zest, brown sugar, soy sauce, rice vinegar, garlic powder, and ginger powder to a small sauce pan.
Whisk over medium-low heat until the sugar dissolves and the sauce starts to bubble.
Whisk the tbsp of cornstarch with 1 tbsp water then whisk it in to the sauce. Bring the sauce up to medium heat, whisking occasionally, until it starts to bubble, thicken, and turn glossy.
Remove from the heat and enjoy immediately on your desired dish.
