Instructions

1. 1

   1. MAKE THE KOMBU DASHI: Combine the dried kombu and 1.5 liters cold water in a medium saucepan. Let soak at room temperature for 30 minutes — this cold extraction pulls maximum glutamate without the slimy texture hot-steeping creates. Slowly bring to 60°C (140°F) over low heat and hold for 20 minutes (use a thermometer — never boil kombu or it turns bitter and mucilaginous). Remove kombu, reserve it, and set the dashi aside.

2. 2

   2. PREP THE RIBS: Pat short ribs completely dry with paper towels — moisture is the enemy of a good sear. Season aggressively on all sides with 1.5 tsp salt and the black pepper. Let rest uncovered at room temperature for 20 minutes while you preheat your oven to 160°C (325°F).

3. 3

   3. SEAR: Heat a large Dutch oven (at least 6-liter capacity) over high heat until smoking. Add neutral oil. Working in two batches to avoid crowding, sear short ribs 3–4 minutes per side until deeply mahogany-brown on all meaty surfaces. Do not rush this step — the Maillard crust is your flavor foundation. Transfer seared ribs to a plate.

4. 4

   4. BUILD THE AROMATICS: Reduce heat to medium. Add onion quarters, smashed garlic, ginger coins, scallion pieces, and the reserved kombu (cut into strips) to the Dutch oven. Cook, stirring occasionally, for 4–5 minutes until onion softens and edges char slightly. Add the chopped Asian pear and dried shiitake mushrooms; stir for 2 minutes. The pear's natural enzymes will tenderize the meat during the long braise.

5. 5

   5. BUILD THE BRAISING LIQUID: In a bowl, whisk together the doenjang, tamari, gochujang, mirin, toasted sesame oil, fish sauce, and rice vinegar until smooth. Pour this paste over the aromatics in the Dutch oven and cook, stirring, for 90 seconds until the paste darkens and becomes fragrant — you're toasting the fermented compounds. Add whole black peppercorns, then pour in all of the kombu dashi. Scrape up any fond from the bottom.

6. 6

   6. BRAISE: Nestle the seared short ribs back into the pot, bone-side up, ensuring they're submerged at least 75% in liquid. Bring to a bare simmer on the stovetop, then cover tightly and transfer to the preheated oven. Braise at 160°C (325°F) for 3 hours, checking at the 2-hour mark — ribs are done when a chopstick slides through the meat with zero resistance and the collagen has melted into the braising liquid.

7. 7

   7. REST AND REDUCE: Remove the Dutch oven from the oven. Carefully transfer ribs to a rimmed baking sheet. Strain the braising liquid through a fine-mesh sieve into a wide saucepan, pressing solids to extract all liquid; discard solids. Skim the fat from the surface (or refrigerate overnight and lift the solidified fat cap — this is the superior method). Bring the defatted liquid to a boil over high heat and reduce by 40–50% until it coats a spoon and tastes intensely savory, about 15–20 minutes. Taste and adjust with a splash of rice vinegar if it needs brightness, or a pinch of salt.

8. 8

   8. MAKE THE WATERCRESS GREMOLATA: While the sauce reduces, combine chopped watercress, toasted black and white sesame seeds, yuzu zest, yuzu juice, grated garlic, sesame oil, and fish sauce in a bowl. Toss gently — you want the watercress to stay vibrant and crisp, not wilted. Season with salt and white pepper. Make this no more than 20 minutes before serving; watercress weeps quickly.

9. 9

   9. GLAZE AND FINISH: Return the short ribs to the Dutch oven (or a broiler-safe pan). Spoon several tablespoons of the reduced braising sauce generously over each rib. Place under a high broiler for 3–4 minutes until the surface lacquers and caramelizes to a sticky, glossy char. Watch closely — the sugars from mirin and pear can go from perfect to scorched in 60 seconds.

10. 10

    10. PLATE: Spoon a mound of steamed rice into each bowl. Place 2 glazed short rib pieces on top, angling the bones for drama. Ladle 2–3 tablespoons of the reduced braising sauce around the base. Pile a generous heap of watercress gremolata directly on top of the ribs. Finish with sliced scallion greens, a pinch of gochugaru, and a final drizzle of toasted sesame oil. Serve immediately.

Variations

• ◆Pressure cooker shortcut: braise in an Instant Pot on high pressure for 55 minutes with a 20-minute natural release. You'll sacrifice some slow-developed complexity, but collagen conversion is nearly identical. Cut the dashi by 200ml, since there's almost no evaporation.
• ◆Vegan version: swap the short ribs for 1.5 kg king oyster mushrooms halved lengthwise plus overnight-pressed firm tofu cubes. Replace fish sauce with 1 tbsp white miso whisked into 1 tbsp rice vinegar. Braise for 45 minutes only. The kombu-doenjang combination still delivers the full glutamate hit.
• ◆Next-day cold noodle bowl: refrigerate the braising liquid overnight, lift the fat cap, and toss the jellied stock with cold cooked buckwheat soba, shredded leftover rib meat, cucumber ribbons, and extra gremolata. It's a naengmyeon-adjacent bowl that may honestly be better than the original dish.
