Cream of Radish and Leek Soup

Oh, how I wish you could taste this soup!  It is heavenly!  Unfortunately, I was the only one in my family to enjoy it.  No one else likes radishes and they didn't even try this one... :(  Well, I truly enjoyed it.  The flavors are absolutely amazing and the radishes give it a little hint of spice.  Absolutely perfect, creamy and delicious!  Enjoy!
-2 Tbs butter
-2 bunches radishes, with tops and bottoms removed, and cut into halves
-3 yukon potatoes, peeled and cubed
-2 leeks, cleaned, with tops removed and thickly sliced
-4 cups chicken broth
-salt and pepper, to taste
-1 cup whole or 2% milk
Melt butter in large sauce pan.  Add the radishes, potatoes and leeks.  Season with some salt and pepper.  Mix well.  Add the chicken broth, give it a good stir and bring to a boil.  Lower the heat, cover and let it simmer for 1 hour.  Using an immersion blender (or working in batches with a regular blender), process until nice and smooth.  Stir in the milk, adjust the seasoning and serve.  Enjoy!
