Follow these simple steps to create your Spicy Gochujang Pork Ribs:

1. Prepare the Ribs: Trim any excess fat from the ribs and remove the silver skin from the underside for better flavor absorption.

2. Make the Marinade: In a bowl, combine gochujang, soy sauce, honey, rice vinegar, sesame oil, minced garlic, grated ginger, brown sugar, and black pepper. Mix well until smooth.

3. Marinate the Ribs: Place the ribs in a large resealable bag or a shallow dish. Pour the marinade over the ribs, ensuring they are well coated. Seal the bag or cover the dish and refrigerate for at least 2 hours, preferably overnight.

4. Preheat the Oven or Grill: If using an oven, preheat it to 300°F (150°C). For grilling, prepare your grill for indirect heat.

5. Cook the Ribs:
– Oven Method: Place the ribs on a baking sheet lined with aluminum foil. Cover loosely with foil and bake for 2 hours. Remove the foil and increase the temperature to 375°F (190°C) for 15-20 minutes, allowing them to caramelize.
– Grill Method: Clean and oil the grill grates. Place the ribs over indirect heat for about 2 hours, periodically brushing with extra marinade. Finally, move them to direct heat for 10-15 minutes for a crispier finish.

6. Rest the Ribs: Once removed from the heat, let the ribs rest for about 10 minutes to allow the juices to redistribute.

7. Slice and Serve: Cut the ribs between the bones and arrange them on a serving dish. Drizzle with extra marinade if desired.

8. Garnish: Sprinkle with sliced green onions and sesame seeds for an appealing presentation.
