OSSO BUCO WITH TOASTED PINE NUT GREMOLATA

Steps:

• 1. Preheat oven to 375°F.
• 2. Season the shank all over with salt and pepper. In a heavy-bottomed, 6- to 8-quart casserole, heat the olive oil until smoking. Place the shank in the pan and brown all over for 12 to 15 minutes, turning with long-handled tongs to sear every surface. Remove the shank and set aside.
• 3. Reduce the heat to medium, add the carrot, onion, celery, and thyme, and cook, stirring regularly, until golden brown and slightly softened, 8 to 10 minutes. Add the tomato sauce, chicken stock, and wine and bring to a boil. Return the shanks to the pan, making sure they are submerged at least halfway; if not, add more stock. Cover the pan with a tight-fitting lid of aluminum foil. Braise in the oven for 2 hours, then remove the cover and cook another 30 minutes, until the meat is nearly falling off the bone.
• 4. Just before the meat is done make the gremolata. In a small bowl, combine the parsley leaves, pine nuts, lemon zest, and horseradish and mix well by hand. Sprinkle with a little salt and pepper and set aside.
• 5. Remove the casserole from the oven and let stand for 10 minutes before carving the shank and dividing among four warmed dinner plates, topped with the gremolata.
