Ingredients

  • 1 6-inch white-corn tortilla
  • 3 tablespoons unsalted butter
  • 1 1/2 cups chopped white onion
  • 4 large cloves garlic
  • 2 1/2 cups chicken stock
  • 1/4 cup heavy cream
  • Kosher salt
  • 1 teaspoon light-brown sugar
  • 3 tablespoons medium-roast coffee beans, finely ground
  • 1 tablespoon cocoa powder
  • 18 teaspoon ground cinnamon
  • 1 2-pound beef tenderloin roast, cut from the large end, trimmed and tied at 1/2 -inch intervals with kitchen twine
  • Kosher salt and black pepper
  • 2 tablespoons extra-virgin olive oil
  • 3/4 pound shiitake mushrooms, stemmed and quartered
  • Sprigs of watercress

Method

  • 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 saute 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, puree 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 saute 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.
