Roasted Cauliflower and Sunchoke Soup

This is not the prettiest soup in the world.  That’s not the most tempting way for a food write to begin selling you on a new recipe, but it’s true.  Though having said that, I said the same thing to the photographer, Cheyenne, as I brought it over for her to shoot, and she took a few snaps, and said, “Oh, I think it’s actually very beautiful.”

(She also like photographing things she determines macabre, like beets).

Ok, it’s not so bad.  especially in a pretty blue mug with sliced scallions.  Sliced scallions make so many things look better.  Jambalaya, anyone?

So, Sunchokes are another terms for Jerusalem Artichokes, and these little tubers may or may not be familiar to you.  They were not familiar to me until recently.  They have a potatoes-on-steroids laste, and look like knobby little chunks of ginger. For roasted sunchokes, click here.

I am realizing now, that a very fancy schmancy little thing to do would be to garnish this soup with some small diced roasted sunchokes/Jerusalem artichokes.  Next time.  Or maybe next life.

The first time I made this soup it was without the few glugs of cream stirred in at the end.  I thought it was good, but with the cream I think it’s much better.  The amount of broth is really dependent on how thin or thickly porridge-like you want your soup to be.  Make sure to use vegetable broth (store-bought or homemade) if there are vegetarians in your family or at your table.
