Preserves are a type of food that has been preserved in jars or other containers. They are usually made from fruits, vegetables, and other ingredients that have been cooked and then sealed in a jar to prevent spoilage. Preserves can be used as a condiment, spread, or topping for various dishes. They are also often used in jams, jellies, and other preserves. Preserves are a popular way to store food for long periods of time, as they can last for several months or even years when stored properly.'
