Celery Bisque with Stilton Toasts

Preparation

1. Step 1

   Melt butter in heavy large pot over medium-high heat. Add celery and leeks. Sauté until celery is slightly softened, about 4 minutes. Add potatoes and 4 cups broth. Bring to boil. Reduce heat to medium-low. Simmer, uncovered, until all vegetables are tender, about 30 minutes. Working in batches, puree soup in blender until smooth. Return to same pot. Whisk in 1/3 cup crème fraîche and cayenne pepper. Season soup to taste with salt and pepper. (Can be prepared 2 days ahead. Cool, then cover and refrigerate. Rewarm over medium heat before serving, adding more broth to thin if desired.)

   Step 2

   Ladle soup into bowls. Swirl 1 to 2 teaspoons additional crème fraîche into each. Sprinkle with parsley, if desired. Serve with Stilton Toasts.
