Absolutely Ultimate Potato Soup

I have made this for many whom have given it the title. This takes a bit of effort but is well worth it. Please note: for those who do not wish to use bacon, substitute 1/4 cup melted butter for the bacon grease and continue with the recipe. (I generally serve this soup as a special treat as it is not recommended for people counting calories.)
Ingredients
  • 1 pound bacon, chopped
  • 2 stalks celery, diced
  • 1 onion, chopped
  • 3 cloves garlic, minced
  • 8 potatoes, peeled and cubed
  • 4 cups chicken stock, or enough to cover potatoes
  • 3 tablespoons butter
  • 1/4 cup all-purpose flour
  • 1 cup heavy cream
  • 1 teaspoon dried tarragon
  • 3 teaspoons chopped fresh cilantro
  • salt and pepper to taste
