Yield: serves 6-8

Ingredients

  • 4 tbsp. unsalted butter
  • 4 medium leeks, white part only, trimmed, washed, and thinly sliced
  • 1 medium yellow onion, peeled and thinly sliced
  • 5 medium floury potatoes, peeled and thinly sliced
  • 5 cups chicken stock
  • Salt
  • 2 cups milk
  • 2 cups half-and-half
  • Freshly ground white pepper
  • 1 cup heavy cream
  • 1 small bunch chives

Instructions

  1. Melt butter in a medium pot over medium heat. Add leeks and onions and cook until lightly golden, 10-15 minutes. Add potatoes, stock, and 1 tbsp. salt and cook until potatoes are tender, 35-40 minutes. Pass soup through a food mill, then press through a sieve into a clean pot. Whisk in milk and half-and-half and season to taste with salt and pepper. Bring to a boil over medium heat, stirring frequently. Set soup aside to let cool.
  2. Press soup again through a sieve into a large bowl. Cover and refrigerate until chilled. Whisk in cream. Refrigerate soup until cold. Serve soup in chilled soup bowls and garnish lavishly with snipped chives.
