Ingredients

  • 4 cloves garlic
  • Kosher salt
  • 1 tablespoon chopped rosemary
  • 1 tablespoon olive oil
  • 2 teaspoons soy sauce
  • 1 teaspoon crushed red pepper flakes
  • 4 (4-inch) English-style bone-in beef short ribs (about 3 pounds)
  • Freshly ground black pepper
  • 1/2 head cauliflower (about 1 pound)
  • 1 tablespoon olive oil
  • Kosher salt, freshly ground pepper
  • 1/3 cup heavy cream
  • 1/2 cup blanched or skin-on hazelnuts
  • 2 stalks celery, halved lengthwise, thinly sliced on a diagonal; plus 1/4 cup celery leaves
  • 1/4 cup chopped parsley
  • 1 tablespoon hazelnut oil or olive oil
  • 1 tablespoon Sherry vinegar or red wine vinegar
  • Flaky sea salt, freshly ground pepper

Method

  • Place racks in upper and lower thirds of oven and preheat to 275°F. Slice garlic, sprinkle with salt, and mash to a paste on a cutting board using the side of a chef's knife; place in a small bowl. Mix in rosemary, oil, soy sauce, and red pepper flakes.
  • Season ribs generously with salt and pepper and place in a medium cast-iron skillet. Coat all over with garlic paste and cover skillet tightly with foil. Cook on upper rack in oven, checking for doneness after 1 1/2 hours, until meat is fork-tender and falling off the bone, 2 1/2-3 hours. Remove from oven.
  • Meanwhile, place cauliflower in a small baking dish. Rub all over with oil; season with salt and pepper. Cover with foil and place in oven next to ribs. Bake until cauliflower is very easily pierced with a paring knife, 1 1/2-2 1/2 hours.
  • Transfer hot cauliflower to a blender and add cream. Blend until very smooth; season with salt and pepper. Place in a medium saucepan and keep warm over low heat.
  • While the ribs and cauliflower are cooking, scatter hazelnuts on a rimmed baking sheet and toast on bottom rack, tossing once, until golden brown, 30-35 minutes. Let cool, then rub together in a kitchen towel to remove skins, if using skin-on nuts. Coarsely chop and set aside.
  • Increase oven temperature to 450°F. Uncover ribs and return to oven, placing on top rack. Roast, basting with fat from skillet every couple of minutes, until a deep brown crust develops, 12-15 minutes.
  • Toss celery, celery leaves, parsley, and reserved hazelnuts in a medium bowl to combine. Drizzle with oil and vinegar and toss to coat; season celery salad with salt and pepper.
  • Serve short ribs over cauliflower puree with celery salad on top.
