#3 – Sugar
It really doesn’t matter if the sugar is brown, white, or even powdered – it will forever be edible. It simply can’t spoil, because bacteria are unable to live in such environment. However, the only thing about old sugar is that it becomes harder each year. But, you shouldn’t worry, as you can do the same thing that you do with honey (put it in hot water) and it will return in its original form. Remember to store it in a cool and dry place!
