  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.
