--------  ------------  --------------------------------
   1      Quart         water
   1      Cup           sugar
   1      Cup           FRESH lemon juice
                        Sparkling Water (not tonic water -- like Perrier)

Preparation:

Mix first three togther. Fill a tall glass 2/3 to 3/4 with Lemon mixture then fill with sparkling water. An intresting variation is to puree some fruit (raspberries, strawberries, etc) with a little superfine or powdered sugar and put that in the glass before adding the the lemonade and water.
