   From: Arizona Cookbook
   
   granulated sugar
   
   Measure oranges and lemons together. Add 5 times as much cold water.
   During next 24 hours, boil hard for an hour. This will reduce the
   quantity one-half. Measure into 4-cup units.  If oranges are overly sweet,
   add 1 tbsp lemon juice for every cup of fruit. Bring to boiling
   point. Boil 8 minutes. Add 3/4 cup sugar for each cup of fruit.
   
   Boil first unit rapidly until it jells -- not more than 10 min. If a
   longer time seems to be necessary, boil the next unit for a longer
   time before the sugar is added. Pour into sterilized glasses and
   cover with paraffin when cold.
