4 cups (2 lbs.) juice
7½ cups (3¼ lbs.) sugar
½ bottle Certo
To prepare juice, crush thoroughly (do not pit or peel) about 4 pounds
fully ripe fruit. Add 3½ cups water, bring to a boil, and simmer,
covered, 30 minutes. 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 11 glasses (6 fluid ounces
each).
