According to this scientific diagram, soup is the most neutral of ideas. If you tell someone you're having soup for dinner, they'll ask what you're eating with it, as if soup were not a meal in itself. That's a tragedy. Soup is right up with bread as a symbol of nourishment. It makes your veggies tasty, and it something you don't even need teeth to enjoy - a treat for either extreme of the age spectrum!

What is it that you think that soup needs to be exciting again? Is it just a special flavor or specific texture? Or do you need gimmicks like tortilla strips or bread bowls? Do you need exotic ingredients?
