In a large bowl, toss the chicken wings with salt, pepper, and minced ginger.
Coat the seasoned chicken thoroughly with potato starch, pressing to ensure a thin, even layer.
Heat vegetable oil in a deep fryer or heavy pot to 350°F (175°C).
Fry the chicken in batches for 8-10 minutes until lightly golden and cooked through; drain on a wire rack.
While chicken rests, combine gochujang, ketchup, honey, soy sauce, garlic, and sesame oil in a small saucepan over medium heat; simmer for 2 minutes until thickened.
Increase the oil temperature to 375°F (190°C).
Perform the second fry by submerging the chicken for 2-3 minutes until deep golden brown and extremely crunchy.
Transfer hot chicken to a large bowl, pour the warm sauce over it, and toss to coat evenly.
Garnish with toasted sesame seeds and serve immediately.
