6 cups (3 lbs.) prepared fruit
8 cups (3½ lbs.) sugar
½ bottle Certo
To prepare fruit, quarter 2 oranges and 1 lemon, seed, slice thin. Add 3
cups water and ⅛ teaspoon soda; bring to a boil, cover, and simmer 15
minutes. Add about 1 pound fully ripe cranberries and simmer, covered,
10 minutes longer. Measure sugar into large kettle. Add prepared fruit,
filling up the last cup with water if necessary. Mix well and bring to a
_full rolling boil_ over hottest fire. Stir constantly before and while
boiling. Boil hard 1 minute. Remove from fire and stir in Certo. Stir
and skim for 5 minutes. Pour quickly. Paraffin at once. Makes about 13
glasses (6 fluid ounces each).
