Pamela L. Brady , Extension Foods Specialist Introduction Jams are thick sweet spreads made by cooking crushed or chopped fruits with sugar.
Jams tend to hold their shape but generally are less firm than jelly.
Well-ripened, yet sound berries, and soft fleshed fruits make good jam. General Method Wash the fruit and crush or chop. Cook in small batches in a large, heavy kettle. Mix the crushed or chopped fruit with sugar. Stir fruit mixture over low heat until sugar dissolves.
