This is a creamy and satisfying soup that is silky smooth with nice nibbles of vegetables that offer a nice change from other potato leek soups. The use of buttermilk and cardomom also provide distinctive flavor to the soup. This is filling enough to use as the centerpiece of a comforting dinner or lunch. You can make this vegetarian by using vegetable broth in lieu of chicken broth. On the day the photo was taken, I omitted the mushrooms for the sake of a mushroom-hating guest. Every spoonful was still delicious.
