1 asian pear, peeled, cored and cut into rough 1-inch chunks
10 medium garlic cloves, smashed and peeled
1 2-inch piece fresh ginger, peeled and roughly chopped
½ cup sake
½ cup soy sauce
⅓ cup white sugar
¼ cup mirin
Ground black pepper
3 pounds thin (⅛- to ¼-inch-thick) bone-in, flanken-cut beef short ribs
Lettuce leaves, to serve
Ssamjang
01 In a blender, combine the pear, garlic, ginger, sake, soy sauce, sugar, mirin and ½ teaspoon pepper. Blend until smooth, 15 to 20 seconds. Pour the mixture into a 9-by-13-inch baking dish. Add the short ribs, turning them to coat with the marinade, and arrange in an even layer; the ribs should be mostly submerged. Cover and refrigerate for at least 2 hours or up to 24 hours, turning them once or twice to ensure they marinate evenly.
02 Prepare a charcoal or gas grill. For a charcoal grill, ignite a large chimney of coals, let burn until lightly ashed over, then distribute evenly over one side of the grill bed; open the bottom grill vents. Heat the grill, covered, for 5 minutes, then clean and oil the grate. For a gas grill, turn all burners to high and heat, covered, for 15 minutes, then clean and oil the grate.
03 Transfer the short ribs from the marinade to a large plate, allowing excess marinade to drip off. Place as many ribs as will comfortably fit on the grill grate (on the hot side if using charcoal). Cook, uncovered, until nicely charred on the bottom, 2 to 3 minutes. Using tongs, flip the ribs and grill until the second sides are nicely charred, about 2 minutes, then transfer to a platter. If not all ribs fit onto the grill, cook the remainder in the same way.
04 Serve the ribs with lettuce leaves and ssamjang. To eat, smear a little ssamjang on a piece of lettuce, cut a piece of meat from the bone and wrap it in the lettuce.
