13. Avocados
It can be tricky to catch avocados at the peak of their ripeness, and they are just not good when they’re too hard or too soft. Eating an under-ripe avocado is like biting into a raw potato, and overripe avocado is mushy and blackened.
Still, it’s only good to refrigerate avocado if you have one that has gotten ripe but you aren’t ready to use it. That can buy you a couple of extra days.
