Classic Vichyssoise (Chilled Leek And Potato Soup) - cooking recipe

Ingredients

4 medium leeks, trimmed and sliced 1/8 inch thick (about 3 cups)
2 large yukon gold potatoes, peeled and sliced 1/8 inch thick (about 4 cups)
2 cups whole milk
kosher salt
1 cup heavy cream
1 tablespoon thinly sliced fresh chives (optional)

Preparation

Combine the leeks, potatoes, milk, and 2 cups water in a 4-quart pot.
Bring to a simmer over medium-high heat. Add 1-1/2 teaspoons salt, reduce the heat to medium low, and simmer until a potato slice falls apart when you poke it with a fork, about 20 minutes. Remove from the heat, stir in the cream, and let cool briefly.
Puree the soup with an immersion blender.
Strain the pureed soup. Let cool to room temperature, stirring occasionally to prevent a skin, and then refrigerate until thoroughly chilled.
Before serving, thin the soup with water or milk if necessary-it should be the consistency of heavy cream. Serve cold, and garnish with chives.
