  1. 2 tablespoons unsalted butter
  2. 2 medium leeks, white and tender green parts, coarsely chopped
  3. 1 1/4 pounds Yukon Gold potatoes, peeled and cut into 1/2-inch dice
  4. Salt and freshly ground pepper
  5. 1 quart chicken stock or low-sodium broth
  6. 1 quart water
  7. 8 cups packed radish greens (from 2 pounds radishes)
  8. 1 cup crème fraîche
  9. 3 tablespoons finely chopped chives
  1. Melt the butter in a large saucepan. Add the leeks and potatoes, season with salt and pepper and cook over moderately low heat, stirring occasionally, until the leeks are softened, about 8 minutes. Add the chicken stock and water and bring to a boil over high heat. Reduce the heat to moderately low and simmer until the potatoes are tender, about 15 minutes. Add the radish greens and crème fraîche and simmer for 2 minutes longer.
  2. Working in batches, puree the soup in a blender on low speed until smooth and flecked with bits of green. Transfer to a large bowl, season with salt and pepper and refrigerate, stirring occasionally, until chilled, about 1 hour. Ladle the chilled soup into bowls, top with the chives and serve.
Make Ahead The soup can be refrigerated for up to 2 days.

Suggested Pairing

A crisp, dry white or sparkling wine will contrast with the creamy soup and blend with the slightly bitter greens. Try a simple French vin de pays or an Italian Prosecco.
