Sunchoke Soup

Made this great soup for dinner, Cream of Sunchoke Soup. Phil and I ordered it at Lovely Hula Hands for my birthday dinner, where it was WAY better, but hey, I'm trying. I've totally messed up the "read more" thing, but if you click on it you'll get the list of ingredients.
Ingredients

Chop, chop chop chop chop.

Sunchokes look really weird.

Some for me, some for the soup!

Add the other vegetables and mustard, and sautee for 10 minutes. 
Add white wine and increase heat, boiling off nearly all the liquid.

In batches, puree the soup mixture in a food processor or blender, then transfer back to pot.
