Title: Lemon butter mousse
 Categories: Desserts
      Yield: 12 Servings
 
    1/3 c  Fresh lemon juice; PLUS:
      3 tb Fresh lemon juice
      1 ts Finely grated lemon zest
    1/4 oz Unflavored gelatin
      1 c  Heavy cream
      6    Eggs; separated, room temp.
    1/4 ts Salt
      3 c  Sifted confectioners' sugar
    1/4 lb Unsalted butter; room temp.
 
  In a small heatproof bowl, stir together the first amount of lemon
  juice and the lemon zest.  Sprinkle on the gelatin and set aside to
  soften for 10 minutes. Set the bowl in a saucepan of hot water over
  low heat and stir to dissolve the gelatin.  Remove from the heat and
  let cool to room temperature.
  
  In a large bowl, whip cream until just stiff.  Cover and refrigerate
  until needed.
  
  In a deep bowl, combine egg whites with the salt. Beat until soft
  peaks form.  Gradually add 1 cup of the confectioners' sugar and beat
  until stiff peaks form.
  
  In another bowl, beat the butter until soft and fluffy. Add 1 cup of
  the confectioners' sugar and beat until smooth. One at a time, add
  the egg yolks, alternating with the dissolved gelatin and the
  remaining 1 cup confectioners' sugar.  Continue to beat until smooth.
  Fold in one-third of the egg whites. Quickly but gently fold in the
  remaining egg whites.
  
  Beat the remaining lemon juice into the whipped cream and fold into
  the mousse.  Turn into a serving dish or stemmed wine glasses, cover
  and refrigerate until chilled and set, about 3 hours.
