Tried your suggestion of using milk instead of water Thermomixer, added 1T veg stock concentrate and mixed the parmesan through the soup rather than sprinkling it on top. It was very nice but looks so bland being just white and thick. Think next time I will make some broccoli soup as well and pour the 2 soups into the bowl at the same time so that one half of the bowl is green and the other white. Saw a photo somewhere once and it looks great. Presentation is as important as taste.
