01 - Rinse the beef short ribs under cold water to remove any bone fragments. Pat thoroughly dry with paper towels.
02 - In a large bowl, combine soy sauce, brown sugar, honey, mirin, sesame oil, minced garlic, grated ginger, grated pear, grated onion, black pepper, green onions, and sesame seeds. Whisk until the sugar completely dissolves.
03 - Add the short ribs to the marinade, turning to coat each piece thoroughly. 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 the ribs from the refrigerator and let them come to room temperature for 15 minutes before cooking.
05 - Remove ribs from the marinade, allowing excess liquid to drip off. Grill for 3 to 4 minutes per side until caramelized and cooked through, with a slight char around the edges.
06 - Transfer the grilled ribs to a serving platter. Sprinkle with thinly sliced green onion and toasted sesame seeds. Serve immediately with steamed rice and kimchi.
