In theory, cornbread should be at the very top of this list. It is, when served with honey butter, one of the most perfect foods on the planet, with its rustic crumble and gentle sweetness reminding you of the bounty of American farmland with every bite. But it gets knocked down a few spots because of just how easy it is to fill up on it. Before you know it, you’ve eaten five pieces of cornbread and have no room for anything else. It’s essentially the same as Mariah Carey’s Christmas album -- the first three times, it’s the best thing ever, but by the fourth time, you want it to disappear forever.
