It wasn’t the best advertising line, but it was undeniably true: Soup is good food.
On a frosty night when the wind is blowing, and the chill sinks deep into your bones, what is it that you turn to? Soup. When you want something warming and comforting after a difficult day, what is it that you most desire? Soup. When you have a cold, what is the only thing that can make you feel better? Soup, especially if it has chicken and noodles in it.
It restoreth the soul. And of course it is always best when your cup runneth over.
At its most elemental level, soup is just water with a bunch of other stuff cooked in it. And that is what makes it so exciting. You can have a free hand to do with it what you will.
