Fruit preserves are preparations of fruits whose main preserving agent is sugar and sometimes acid, often stored in glass jars and used as a condiment or spread. There are many varieties of fruit preserves globally, distinguished by the method of preparation, type of fruit used, and place in a meal.

Jam is a thick mixture of fruit, pectin, and sugar that is boiled gently but quickly until the fruit is soft and has an organic shape, yet is still thick enough that it spreads easily and can form a blob. In addition to being a spread, jams are also good for fillings.
