Roasted Celery Root and other Oddities

Celery root is a strange strange vegetable.  It certainly does not look appetizing in its raw root form.  It's mostly eaten here grated as a salad with lots of mayo and cream.  It's interesting, though, because it has the pungent taste of celery but without all the stalks.  The root is white and can be used in purees such as mashed potatoes or soup.
Why doesn't anybody ever roast the thing?  Afraid of too much textural confusion?  Roasting is my favorite way of subliming quality ingredients in their own fragrance.  I added some other oddities such as white turnip and sweet potato, then some other tid bits to make it a bit more colorful than just.. white.
Then it ended up making enough for 5 people, although it was originally just for me.  No worries... I am quite good at bringing the best out of individuals..
