Jams and jellies are a great way to preserve fruit. They are made by boiling fruit in water and sugar until it reaches a setting point. The fruit is primarily preserved by the action of sugar. As long as jams and jellies are made and stored appropriately (with clean equipment following a recipe then stored in a dry, cool place in an airtight container), they have a long shelf-life.
