When Martha made this recipe on Cooking School episode 411, she used bone-in short ribs and omitted the skewers. She also doubled the marinade but did not use any apple juice. Hot kimchi (store-bought is fine) is great with the sweet, gingery ribs.
Combine soy sauce, vinegar, sugar, Worcestershire sauce, juice, ginger, sesame seeds, garlic, and scallions in a shallow dish. Add ribs. Cover, and refrigerate at least 8 hours.
Preheat grill to medium-high. Thread meat onto skewers, and grill until cooked through, 1 to 3 minutes per side. Serve with kimchi, rice, and lettuce.
