Very simple, filling, and soothing soup. If you want to add anything to spice it up, I would recommend using something like a ground white pepper to give it a kick. Or even to simmer with a 2 to 3 thin slices of ginger. I agree with the other poster that this is a very easy recipe to tweak by adding things like different veggies and such. (Mmmmm, mushrooms!) Chinese cuisine has flavors that range from subtle to loud. There is not one fixed note. I'm going to make the comment here that miso paste, lemongrass, etc are not Chinese ingredients. Miso is traditionally Japanese, and lemongrass is a staple in Southeast Asian countries. Both would probably make delicious variations as this is a simple soup, but just wanted to put this out there in case anyone reading is searching for authenticity.
