Leek and potato soup

Leek soup, or Leek and Potato soup, is a soup based on potatoes, leeks, broth (usually chicken), and heavy cream. Other ingredients used may be salt, pepper, and various spices. Generally the potatoes are diced and cooked in broth, while the leeks are chopped and sautéed. After this, all ingredients are combined and stirred. Chives may be used for garnish. Like many other soups, it is often eaten with bread and butter. Leek soup is traditionally associated with Wales, as leeks are regarded as the national vegetable of Wales, and is an important item of Welsh cuisine. In Romania, this soup is popular and known as Ciorbă de praz, and in France it is called Soupe aux poireaux. One variant of leek soup is vichyssoise, which is generally served cold.
