There are very, very few recipes I don't tweak. I usually add a little, subtract a little, and change it up to fit what my family likes to eat. This recipe is absolutely, positively perfect just the way it is. It seems impossible that only 3 ingredients -- Cauliflower, Onion and Water -- could yield such a flavorful soup. It's creamy and velvety smooth without adding any cream, and it just goes to show that the purest and simplest ingredients can result in a perfect dish.
