           CHESTNUT MASCARPORLE MOUSSE:

    3/4 c  Heavy cream
      4 oz Chestnut puree
    1/2 c  Confectioners' sugar
      1 ts Vanilla extract
 
  Make the tart shell:
  
  1.In a food processor fitted with the metal chopping blade, combine
  the flour, sugar, salt, and cocoa powder. Pulse the machine eight to
  nine times to blend. Scatter the butter over the flour mixture and
  pulse the machine until the butter is cut into the flour and the
  mixture resembles coarse meal. Add the yolks and continue to process
  in on/off pulses only until the mixture is evenly incorporated and
  the particles begin to hold together. Scrape the dough onto a work
  surface and form it into a ball. Flatten it into a disc and wrap in
  plastic wrap. Chill 1 hour.
  
  2.Position a rack in the center of the oven and preheat to 350
  degrees F.
  
  3.Remove the chilled disc from the refrigerator. Place the dough
  between two pieces of plastic wrap and roll the dough into a small
  round. Lift and rotate the dough one quarter turn after each roll.
  Continue rolling until the circle measures approximately 14 inches in
  diameter and is abut 1/8 inch thick. Remove the top layer of plastic
  wrap.
  
  4.Carefully roll the dough around the rolling pin and transfer it to a
  12-inch fluted tart pan with a removable bottom. Unroll the dough
  into the pan. Lift the edges of the dough and gently press the dough
  into the bottom and up the sides of the pan. Trim off any excess
  dough. Refrigerate the dough for 20 to 30 minutes, until firm.
  
  5.Bake the tart shell 20 to 30 minutes or until set. Place on a wire
  rack and cool completely.
  
  Make the chocolate cream:
  
  1.Place the chopped chocolate in a medium bowl and set aside.
  
  2.In a non-corrosive medium saucepan bring the sour cream, heavy
  cream and 1/4 cup of sugar to a boil over medium-high heat.
  
  3.In a large bowl using a hand-held electric mixer, beat the eggs, egg
  yolks, cornstarch and the remaining 1/4 cup of sugar at medium speed
  until pale. Whisk one-third of the hot cream mixture into the egg
  mixture and return the whole mixture to the pan. Cook over
  medium-high heat while constantly stirring with a whisk for 3 to 5
  minutes or until thick. Pour the thickened mixture over the reserved
  chocolate and whisk until incorporated. Scrape the mixture into the
  prepared crust and smooth the top with a rubber spatula. Chill in the
  refrigerator for 2 hours.
  
  Make the chocolate mascarporle topping:
  
  1.In a 4 1/2-quart bowl of a heavy-duty electric mixer, using the
  wire whip attachment, combine the mascarpone, heavy cream, chestnut
  puree, confectioners' sugar and vanilla. Beat on medium-high speed
  until soft peaks form. Place the mixture in a pastry bag fitted with
  a medium star tip and pipe in a shell pattern covering the top of the
  chilled tart. Refrigerate the tart for 1 hour before serving. Posted
