Jam story

Fruit preserves are preparations of fruits, vegetables and sugar, often canned or sealed for long-term storage.

The ingredients used and how they are prepared determine the type of preserves; jams, jellies, and marmalades are all examples of different styles of fruit preserves that vary based upon the fruit used. In English, the word, in plural form, "preserves" is used to describe all types of jams and jellies.
