4 cups (2 lbs.) juice
7 cups (3 lbs.) sugar
1 bottle Certo
To prepare juice, stem (do not pit) and crush about 2 pounds fully ripe
cherries. Crush about 1½ pounds fully ripe gooseberries. Combine fruits.
Add ¼ cup water, bring to a boil, cover, and simmer 10 minutes. 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 hot jelly at once. Makes about 11 glasses (6 fluid ounces
each).
