I've made potato soups that included bacon, cream, half n half, cheese, carrots, a variety of spices, etc, but I cannot call them "potato soup." My wife ate the soup above so often when young that the words "potato soup" create an expectation against which anything I make is measured. After hearing "that's not potato soup" too many times to count, I now name any potato soup I make something else, and she loves it with no comparisons.
It pays to pay attention.
