      Yield: 20 servings 
  
      1    Sheet puff pastry -- 18 x 
     11    " 
      3 tb Honey mustard 
      4 oz Prosciutto -- thinly sliced 
      1 c  Parmesan cheese -- freshly 
           Grated 
      1    Egg 
      2 ts Water 
  
  Place the puff pastry on a work surface and spread the mustard over the 
  top.  Arrange the prosciutto evenly over the mustard to cover all the 
  pastry, and then sprinkle with the Parmesan.  Lightly press the cheese 
  into the prosciutto with a rolling pin. 
  starting at one long edge, roll up the puff pastry like a jelly roll just 
  to the middle of the dough; then roll up the other side in the same 
  fashion, making two rolls that meet in the center.  Using a serrated 
  knife, cut the rolls crosswise into 1/2" slices.  Place the slices on 
  cookie sheets lined with parchment paper and press lightly with your hands 
  to flatten.  Refrigerate for 15 minutes. 
  Preheat oven to 400 degrees. 
  Beat the egg and water together in a small bowl.  Brush the top of each 
  palmier with the egg wash.  Bake until puffed and lightly golden, about 10 
  minutes.  Serve warm or at room temperature.
