3½ cups (1¾ lbs.) juice
7½ cups (3¼ lbs.) sugar

To prepare juice, cut about 3 pounds of fully ripe red-stalked rhubarb
into 1-inch pieces and put through food chopper. Place fruit 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.
