Corn
Being an Indiana boy, this one is near-and-dear to my heart. Corn is meant to be sweet and delicious, not dull, tasteless, and sad. This is what happens to corn once you put it in the fridge, though. Like NEVER.
If you do it for a day or two, it is not the worst move in the world, but any longer can cause it to lose its sweetness. And what is corn if it isn’t buttery and super sweet? You never want to keep it in the fridge TOO long as it dehydrates corn. Can you say rubbery corn? Gross.
