To ensure the longevity of onions, proper storage is essential. Onions should be kept in a cool, dark place and away from other fruits and vegetables to prevent moisture buildup. Dried onions, such as onion powder and flakes, can be stored for an even longer time, providing convenience and flavor in your pantry.
