Method

  1. Split the leek whites into quarters, wash them thoroughly, then slice them finely.
  2. Sweat them in the butter, covered, over low heat for 12 minutes without letting them colour; vichyssoise must stay very pale.
  3. Add the diced potatoes and the stock, bring to the boil and simmer for 18 minutes, until the potatoes crush easily.
  4. Blend at length, then push the soup through a fine sieve for a perfectly silky texture.
  5. Stir in the cream and season generously with salt and white pepper, remembering that cold dulls seasoning.
  6. Chill for at least 4 hours and serve very cold, scattered with finely snipped chives and a twist of pepper.

Vichyssoise was invented in New York by a French chef homesick for the leek soup of his childhood. Always taste it once cold: a chilled soup needs noticeably more salt than a hot one.

Frequently asked questions

Why does my vichyssoise taste flat once chilled?

Because it was seasoned while hot. Cold markedly dulls the perception of salt: a soup seasoned perfectly hot tastes bland ice-cold. Taste and adjust after the four hours in the fridge, not before.

Why use only the white of the leeks, and keep them from colouring?

Vichyssoise should stay very pale, close to ivory. The green parts tint it, and the slightest browning in the pan brings toasted notes and a beige cast. Sweat them covered, over low heat, for twelve minutes.

Is passing it through a sieve really necessary?

It is what separates a vichyssoise from an ordinary leek soup. However long you blend, fine leek fibres remain, and the sieve catches them. Served cold, where nothing masks the texture, the difference is very noticeable.
