Follow these steps to create your own Spicy Korean Fried Chicken:

1. Prep the Chicken: Rinse the chicken wings or drumsticks under cold water and pat them dry with paper towels.
2. Marinate: In a bowl, combine the buttermilk, gochujang, soy sauce, honey, minced garlic, and grated ginger. Add the chicken, ensuring it’s well-coated. Cover and refrigerate for at least 30 minutes.
3. Prepare the Breading: In a separate bowl, mix the flour, cornstarch, baking powder, salt, and black pepper.
4. Heat the Oil: In a deep pan or fryer, heat oil to 350°F (175°C).
5. Bread the Chicken: Remove the chicken from the marinade, allowing excess to drip off. Dredge each piece in the flour mixture, ensuring an even coating.
6. Fry the Chicken: Carefully place a few pieces of chicken in the hot oil. Fry until golden brown and cooked through, about 8-10 minutes per batch. Use a thermometer to check the internal temperature (165°F or 74°C).
7. Drain the Chicken: Remove the fried chicken from the oil and place it on a paper towel-lined plate to drain excess oil.
8. Prepare the Sauce: In a saucepan, combine the remaining gochujang, soy sauce, honey, rice vinegar, and a splash of water. Heat over medium heat, stirring until combined.
9. Coat the Chicken: In a large bowl, toss the fried chicken with the sauce until evenly coated.
10. Garnish: Transfer the chicken to a serving platter, sprinkle with sesame seeds and sliced green onions for added flavor and presentation.
