Making jam involves both chemical and physical changes. Chemical changes occur when the fruit's natural sugars break down during cooking, leading to caramelization and the creation of new complex flavors. Physical changes occur when the mixture thickens as pectin molecules form a gel-like structure to give the jam its characteristic texture.
