Ingredients

1. 1 tablespoon dried porcini mushrooms
2. 1 1/2 teaspoons black peppercorns
3. 1 teaspoon kosher salt
4. 1 1/2 teaspoons ground coriander
5. 1 1/2 teaspoons powdered ginger
6. 1 1/2 teaspoons smoked sweet paprika
7. 1/2 teaspoon ground cloves
8. 5 pounds flanken-style beef short ribs, 1 inch thick, boned and trimmed of excess fat
9. 2 tablespoons extra-virgin olive oil
10. 1 medium onion, thinly sliced
11. 1 large carrot, thinly sliced
12. 2 inner celery ribs, thinly sliced
13. 2 garlic cloves, thickly sliced
14. 2 cups dry red wine
15. 2 cups beef stock or low-sodium broth
16. 1/4 cup sugar

Directions

1. Preheat the oven to 300°. In a spice grinder, pulse the porcini, peppercorns and salt to a fine powder. Add the coriander, ginger, paprika and cloves and pulse to combine. Rub the spice blend all over the beef short ribs.
2. Heat the oil in a large skillet. Add the short ribs and cook over moderate heat, turning, until lightly browned all over, about 12 minutes; don’t let the spices burn.
3. Scatter the onion, carrot, celery and garlic in a medium roasting pan. Set the short ribs on top, cover tightly with foil and roast for about 2 1/2 hours, until tender.
4. Meanwhile, pour off the fat in the skillet and return it to high heat. Add the wine, stock and sugar and bring to a boil, scraping up any bits from the bottom of the pan. Simmer over moderately high heat until reduced to 1 cup, about 15 minutes. Transfer the glaze to a heatproof cup.
5. Preheat the broiler. Transfer the short ribs to a plate and pour the pan juices and vegetables into a bowl. Skim off all of the fat. Transfer the pan juices and vegetables to a blender. Add 1/2 cup of the glaze and puree the pan sauce until very smooth.
6. Return the short ribs to the roasting pan and brush with 1/4 cup of the glaze. Broil 8 inches from the heat for about 3 minutes, until caramelized and sizzling. Turn the ribs and repeat the process with the remaining 1/4 cup of glaze. Serve the ribs with the pan sauce.

Make Ahead

The short ribs can be prepared through Step 3 and refrigerated overnight. Broil just before serving.
