Jerusalem Artichoke Soup

A nice, simple soup of Jerusalem artichokes, though not really anything special.

I'm not really sure about the beetroot. For one, it's decoration only - don't go out of your way to do this if you don't mind not having any. Second, I'm not sure whether it's supossed to be raw or cooked beetroot. As it doesn't say anything, I would expect raw beetroot. On the other hand, when frying it burns very quickly, and according to DB even before the beetroot is cooked properly. The ones in the picture were red just a few moments before, and now look at them...
