4 1/2 c. prepared fruit, about 1 1/2 qt. fully ripe berries
2 tbsp. lemon juice (1 lemon)
7 c. (3 lb.) sugar
1 bottle Certo fruit pectin

Prepare fruit. Thoroughly crush, one layer at a time. Measure 4 1/2 cups into a very large saucepan. Squeeze the juice from 1 lemon, measure 2 tablespoons into saucepan with berries. Add sugar.

Place over high heat. Bring to a full rolling boil and boil hard 1 minute, stirring constantly. Remove from heat, at once stir in Certo. Skim off foam with metal spoon. Then stir and skim for 5 minutes to cool slightly, to prevent floating fruit. Ladle into glasses. Cover at once with 1/8 inch hot paraffin.
