Potato Leek Soup With Cheese Rinds

• 3 tablespoons butter
• 1 bunch leeks (about 4), dark green parts removed
• 1 teaspoon salt
• 1/4 teaspoon freshly ground black pepper
• 2 pounds yukon gold or russet potatoes, peeled
• 6 cups chicken broth (or vegetable broth)
• 3 pieces Parmigiano Reggiano or Grana Padano cheese rinds (about 7 ounces)

1. To clean the leeks, cut off the dark green tops and the root end. Split each leek longways and separate the layers. Rinse them thoroughly in cold water to remove all the hidden sand. Melt the butter in a large soup pot or sauce pan over medium-low heat. When the butter has melted add the leeks, salt and pepper. Allow the leeks to cook slowly until they are soft and translucent, about 10 minutes.
2. Add the potatoes, broth and cheese rinds and bring to a simmer. Allow the soup to simmer on low heat for about 30 minutes, or until the potatoes are soft but not yet falling apart and the cheese rinds are well softened.
3. Remove the cheese rinds and puree the soup using either an immersion blender or stand blender. (If you use a stand blender be very careful to vent the top of the blender and cover with a towel so you don't burn yourself or end up with a soup covered kitchen). If you want to leave the softened cheese rinds in the soup, chop them up and return them to the pureed soup. Season the soup with salt and pepper to taste and serve hot.
