4½ cups (2¼ lbs.) juice
7½ cups (3¼ lbs.) sugar

To prepare juice, crush thoroughly about 1½ pounds fully ripe currants.
Add ½ cup water and bring to a boil. Crush thoroughly or grind about 1½
quarts fully ripe strawberries. Combine fruits; 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
