11 Foods You Didn’t Know that Last for Years 

Brown sugar and salt can last indefinitely

Brown sugar has an unlimited shelf life, but it must be stored in a jar with a properly sealed lid so that its quality remains the same. Therefore, it is very important to store it in favorable conditions because this way we can enjoy it longer. “Brown sugar can last indefinitely, but will likely need to be softened,” Kaplan says.

“Salt is one of the world’s oldest flavorings, has a plethora of other uses, and it lasts indefinitely. Place salt in a sealed container or ziplock bag, and keep it in a cool dry area. Unless dirt or bugs manage to get it, you are good to go,” says Caleb Backe, health and wellness expert for Maple Holistics.
