Avocados
According to specialists and avocado producers, [1] it is best to store avocados at room temperature until they’re fully ripened, because they may never ripen properly if you refrigerate them too soon. However, it is best and most advised to refrigerate them after they are ripe as it can help extend their lifespan by a few extra days. If you have cut your avocado and want to save the other half for later, sprinkle it with a little lemon juice, pop it into an airtight container and place it in the refrigerator. That should keep it safe till the next time you want to use them.
