I like sweet potatoes, can you tell?

Another favorite here, at least for Layn and I, is my sweet potato soup recipe.  This is comfort food at its best.  When I am coming down with a cold or the weather outside just says, "bundle up and pamper yourself" I will put a pan of this on and sit down with a good book.

Sweet Potato Soup
1/2 stick unsalted butter
1 onion chopped
4 cloves garlic minced
16 ounces chicken broth
2 bay leaves
3 sweet potatoes peeled and chopped
1 c heavy cream

Heat butter in a heavy saucepan over med. heat.  Add the onions and garlic and cook until the onions are tender, stir occasionally.
Stir in the broth, bay leaves, black pepper, and potatoes and heat to a boil.  Reduce the heat to low. Cover and cook until the potatoes are tender.
Stir in the heavy cream and cook until the mixture is hot and bubbling. Remove and discard the bay leaves.
Puree with a blender or immersible blender until mixture is smooth.  Adjust salt and pepper to taste.  Serve with a dollop of sour cream on top.
