01 - Rinse the beef short ribs under cold water to remove bone fragments. Pat dry thoroughly with paper towels.
02 - In a large bowl, whisk together soy sauce, brown sugar, honey, mirin, sesame oil, minced garlic, grated ginger, grated pear, grated onion, black pepper, green onions, and sesame seeds. Stir until the brown sugar completely dissolves.
03 - Add the short ribs to the marinade, turning each piece to ensure thorough coating. Cover the bowl and refrigerate for at least 4 hours, preferably overnight for maximum flavor penetration.
04 - Preheat a grill or grill pan over medium-high heat. Remove ribs from the refrigerator and let excess marinade drip off.
05 - Grill the ribs for 3 to 4 minutes per side until caramelized and cooked through, developing a slight char around the edges for authentic flavor.
06 - Transfer the grilled ribs to a serving platter. Sprinkle with thinly sliced green onion and toasted sesame seeds. Serve immediately while hot, accompanied by steamed rice and kimchi.
