Certo: A Short Cut to Better Jams and Jellies

by General Foods Corporation

CANNED PINEAPPLE JAM

4 cups (2 lbs.) prepared fruit

7 cups (3 lbs.) sugar

1 bottle Certo

To prepare fruit, use canned crushed pineapple. Add juice of 2 medium lemons. Measure sugar and prepared fruit into large kettle, mix well, and bring to a full rolling boil over hottest fire. Stir constantly before and while boiling. Boil hard 1 minute. Remove from fire and stir in Certo. Stir and skim by turns for just 5 minutes to cool slightly, to prevent floating fruit. Pour quickly. Paraffin at once. Makes about 11 glasses (6 fluid ounces each).
