Pour the sauce through a wire mesh sieve into a bowl to remove any cornstarch lumps. Place a piece of plastic wrap on top of the sauce, ensuring the plastic wrap is touching the sauce to prevent a skin from forming; cool to room temperature, about 20 minutes.
Move sauce to refrigerator and chill completely cold, at least 30 minutes.
