Potato Leek Soup

2 c. chicken broth (I have also used vegetable broth to make it vegetarian)
3 med. potatoes
1 lg. leek
1/2 c. sour cream
1/2 T chives
1 c. milk
1/2 t salt

cut potato into cubes & slice the leek. Put the leek, potatoes, broth & salt in the pan. Bring to a boil and take the heat down to a simmer. cook 15-20 mintues. With a hand mixer, puree ingredients. (or put in a blender. I like the hand mixer though because it leaves some chunks) Stir in sour cream, milk & chives.
