Tropical Fruit Champagne Granita
  
      1/2  c             sugar
      1/2  c             water
    3      c             fresh pineapple chunks
    4      c             passion fruit juice -- chilled
      3/4  c             Champagne -- chilled
 
 In saucepan bring sugar and water to a boil, stirring until sugar is
 dissolved, and cool syrup.
 
 In a blender or food processor puree pineapple with 1/4 c plus 2 tbsp syrup
 (reserve remaining syrup for another use).  Stir in nectar or juice and
 Champagne.  Transfer pineapple mixture to a shallow metal baking pan and
 freeze, stirring and crushing lumps with a fork every hour, until mixture is
 firm but not frozen hard, about 3 to 4 hours.  Granita may be made 2 days
 ahead and frozen, covered.  Just before serving, scrape granita with a fork
 to lighten texture.
 
 Scoop granita into serving bowls.
