The best place to store jam is in a cool, dark place, such as a pantry or cupboard, before it is opened. Once opened, it should be refrigerated to maintain freshness and prevent spoilage. Always ensure the jar is tightly sealed to keep out air and moisture. Proper storage helps preserve the flavor and quality of the jam.
The pop-up tops on jarred food are there to tell you if the item had been previously opened. These can fail, but a good rule of thumb is to return the item if that is "popped-up" before you open it.
