      1    Grapefruit 
      3    Oranges

  Makes about 18 jelly glasses. 
   
  Scrub, cut in halves, remove seeds and slice into very small pieces. 
   
  Measure the fruit and juice and add 3 times the amount of water. Soak for 
  12 hours.  Simmer for about 20 minutes. Let stand again for 12 hours. 
   
  For every cup of fruit and juice add 3/4 cup sugar. Cook ingredients in 
  small quantities about 4-6 cups at a time until they form a jelly. Check by 
  the sheet test with a spoon or use a thermometer 8 degrees F above the 
  boiling point of water for your altitude. 
   
  Pour into prepared jars, seal and process. Source: Joy of Cooking 1974
