01 - Rinse beef short ribs in cold water to remove bone fragments. Pat thoroughly dry with paper towels.
02 - In a large bowl, whisk together soy sauce, mirin, water, brown sugar, honey, sesame oil, grated pear, grated onion, garlic, ginger, black pepper, chopped scallions, and sesame seeds until sugar dissolves completely.
03 - Add ribs to marinade, ensuring full coating. Cover and refrigerate minimum 4 hours, preferably overnight, turning occasionally for even flavor distribution.
04 - Preheat grill or grill pan to medium-high heat.
05 - Remove ribs from marinade, allow excess to drip off. Grill 3-4 minutes per side until caramelized and cooked through with slightly charred edges.
06 - Let ribs rest 5 minutes. Slice into pieces if desired. Garnish with sliced scallions and sesame seeds. Serve hot with steamed rice and kimchi.
