Wash chicken wings and pat dry. In a bowl, mix salt, black pepper, and ginger with the chicken. Let it marinate for at least 2 hours in the fridge.
After marinating, coat the chicken evenly with cornstarch.
Heat vegetable oil in a deep fryer or large pot to 350°F. Fry the chicken in batches until golden brown, about 6 minutes per batch. Remove and drain on a rack.
Increase oil temperature to 375°F. Return chicken to fry for an additional 3 minutes, or until crispy and cooked through. Drain on a rack.
Combine soy sauce, rice wine, gochujang, honey, sugar, minced garlic, water, and rice vinegar in a saucepan.
Bring to a simmer and cook until slightly thickened, about 5 minutes. Adjust flavor by adding more sugar or gochujang if needed.
Toss fried chicken in the sauce until evenly coated. Serve immediately.
