COFFEE-ROASTED FILLET OF BEEF

Steps:

• Seed, stem and cut the chilies into pieces. Tear the tortilla into pieces. Set both aside. In a saucepan, melt 1 tablespoon butter over medium-high heat. Add the onion and garlic and sauté until translucent, about 3 minutes. Add the chilies and tortilla and cook over medium-low heat, stirring, until softened. Pour in the stock, bring to a boil and then simmer, partly covered, for 10 minutes. In a blender, purée the hot mixture until smooth. Pour through a fine sieve set over a saucepan, pressing on the solids. Discard the solids. Whisk in the cream, 1 teaspoon salt and the brown sugar. Season to taste.
• Preheat the oven to 400 degrees. In a bowl, whisk together the coffee, cocoa and cinnamon. Pat the beef dry and rub with 2 teaspoons salt and 1 teaspoon pepper; then rub with oil. Sprinkle the coffee mixture over a sheet of wax paper and coat the beef in it. Place the beef on a rack set in a roasting pan and let stand at room temperature for 30 minutes.
• Roast the beef for 10 minutes; then lower the temperature to 250 and cook for an hour more, or until the meat reaches 130 degrees. Let stand, loosely covered with foil, for 10 minutes. (The meat will continue to cook, reaching about 135 degrees.)
• Bring the broth to a boil and simmer until just thick enough to coat the back of a spoon. Cover and keep warm.
• In a large skillet, melt the remaining butter over medium-high heat. Add the mushrooms and sauté until golden. Season with salt and pepper.
• Remove the twine and cut the beef into 1/2-inch-thick slices. Spoon just enough broth to cover the bottoms of 4 to 6 shallow, wide soup bowls. Add 2 to 3 slices of beef, spoon more broth over the beef if desired and top with mushrooms and watercress.
