Follow these instructions for a perfectly caramelized short rib dish:

1. Prepare Beef: Rinse the beef short ribs under cold water and pat dry with paper towels.
2. Make Marinade: In a large bowl, whisk together the soy sauce, brown sugar, rice vinegar, hoisin sauce, ginger, garlic, sesame oil, chili paste, and black pepper.
3. Marinate Beef: Place the short ribs in a large resealable bag or bowl. Pour the marinade over the beef, ensuring it’s well coated. Seal the bag or cover the bowl and refrigerate for at least 2 hours, preferably overnight for maximum flavor.
4. Preheat Oven: Preheat your oven to 325°F (160°C).
5. Sear Beef: In a large skillet over medium-high heat, sear the marinated short ribs on all sides until browned, about 3-4 minutes per side.
6. Transfer to Roasting Pan: Place the seared beef in a roasting pan. Pour any remaining marinade over the ribs.
7. Cover and Roast: Cover the roasting pan with aluminum foil and place it in the preheated oven. Roast for about 3-4 hours or until the meat is fork-tender.
8. Remove Foil to Caramelize: In the last 30 minutes of cooking, remove the foil to allow the surface to caramelize.
9. Check Tenderness: The beef is ready when it can be pulled apart easily with a fork. If not, roast a little longer.
10. Rest and Serve: Once cooked, remove the short ribs from the oven and let them rest for 10-15 minutes before slicing. Garnish with chopped green onions and sesame seeds.

This process will guide you in creating a luscious dish that will impress all who partake.
