Chilled potato-leek soup, orVichyssoise, is an excellent budget dish to have up one's sleeve. At its most basic, the soup's humble ingredients combine to form a silky, luxurious meal far greater than the sum of its parts. In other words: I eat it quite a bit. But I'd never heard of anything likeHugh Fearnley-Whittingstall'sverdant version before. The velvety green soup in his new cookbookRiver Cottage Vegcontains not only the potatoes and leeks, but also a couple of cucumbers and heads of butter lettuce as well. Even crazier is the fact that hecooksboth of these ingredients before blitzing the mess in a blender. Yet, it works. The greenery adds a refreshing touch and brilliant color to the soup, and the dollop of creme fraiche at the end is the perfect tangy-rich note to finish.

Why I picked this recipe:Cooked cucumber and cooked lettuce? I had to try it.

What worked:Everything, from the ingredient list to the finishing touches, worked brilliantly.

What didn't:No problems here.

Suggested tweaks:You could substitute spinach or another soft leafy green for the Little Gem if you still can't wrap your head around cooking lettuce. The croutons are a nice addition, but if you want to skip them, the soup doesn't suffer.

  • 2 tablespoons (60g) butter
  • 2 leeks, trimmed (white and pale green parts only) and sliced, or 1 large onion, sliced
  • 1 large, starchy potato (about 8 ounces/250g), peeled and cut into large chunks
  • 1 quart vegetable stock
  • 2 cucumbers, peeled and cubed
  • 2 Little Gem or butterhead lettuces, shredded
  • 3 tablespoons heavy cream or crème fraîche
  • Sea salt and freshly ground black pepper
  • For the croutons:
  • 1/4 cup (60ml) canola or olive oil
  • 4 slices of bread, crusts removed, cut into cubes
  • To finish:
  • Chopped chives
  • 鲜奶油或奶油fraiche

Directions

  1. Melt the butter in a large saucepan over medium-low heat. Add the leeks or onion, cover, and sweat gently for about 10 minutes, until soft. Add the potato and stock. Bring to a boil, then simmer for about 10 minutes, until the potato is almost cooked. Add the cubed cucumbers and shredded lettuce, return to a boil, and simmer for a further 4 minutes.

  2. Scoop out the potato chunks and rub them through a sieve, run them through a food mill, or press them through a potato ricer into a large bowl (whizzing them in a blender would make the soup gluey). Purée the simmered mixture in a blender, add to the sieved potato, and stir well. Stir in the cream or crème fraîche and season with salt and pepper. Leave to cool completely, then chill for a couple of hours.

  3. Meanwhile, make the croutons. Heat the oil in a frying pan over medium-high heat. Add the bread and fry, turning often, for a few minutes, until golden brown. Leave to cool.

  4. Serve the chilled soup topped with a swirl of cream or crème fraîche, chopped chives, and croutons.
