3 cups (1½ lbs.) juice
6½ cups (2¾ lbs.) sugar
1 bottle Certo
To prepare juice, pare 2 medium, fully ripe pineapples. Chop very fine
or grind. Place in jelly cloth or bag and squeeze out juice. Measure
sugar and juice into large saucepan and mix. Bring to a boil over
hottest fire and at once add Certo, stirring constantly. Then bring to a
_full rolling boil_ and boil hard ½ minute. Remove from fire, skim, pour
quickly. Paraffin at once. Makes about 9 glasses (6 fluid ounces each).
