Cauliflower soup

This started off as a roasted cauliflower with a cheese and porcini enhanced béchamel poured on it, the product of a rainy day and some boring cheddar in the fridge. The next day, I threw it all in a pot, added some more mushrooms, buttermilk and water, and once it was totally soft stick blended the whole thing into this creamy goodness. Mushrooms and cauliflower really get along, and the combination of cheese, milk, and buttermilk really elevated the earthy flavors.
