The inclusion of fennel and a dash of Pernod puts a sophisticated spin on the classic chilled potato soup. 

 
  Ingredients

• 2 tablespoons (1/4 stick) butter
• 2 tablespoons olive oil
• 5 cups thinly sliced fennel bulb (about 3 small fennel bulbs)
• 2 onions or leeks, sliced
• 1 pound small potatoes, unpeeled, cut into 1/2-inch pieces
• 4 cups chicken stock or canned low– salt chicken broth
• 2 tablespoons Pernod

• 2 cups half and half

 
Preparation
Melt 2 tablespoons butter with 2 tablespoons olive oil in heavy large pot over medium heat. Add sliced fennel and onions/leeks. Cover and cook until fennel is tender, stirring occasionally, about 15 minutes. Add potatoes and chicken stock; increase heat and bring to boil. Reduce heat, cover and simmer until potatoes are very tender, about 30 minutes. Remove from heat. Mix in Pernod. Season to taste with salt and pepper.
Working in batches, puree soup in blender. Transfer soup to large bowl. Mix in 2 cups half and half. Season soup to taste with salt and pepper. Cool slightly. Chill soup uncovered until cold, then cover and refrigerate. (Can be prepared 1 day ahead. Keep refrigerated.)
