Ingredients

  • 2 tablespoons olive oil, plus extra for drizzling
  • 1 carrot, finely chopped
  • 2 celery ribs, finely chopped
  • 1 white onion, finely chopped
  • 1 leek, finely chopped
  • 12 ounces brown lentils, soaked overnight
  • 1 rosemary sprig
  • 1 sprig fresh sage
  • 2 fresh bay leaves
  • 1 12 pints vegetable stock
  • 2 teaspoons red wine vinegar
  • 6 tablespoons chopped flat leaf parsley
  • salt & freshly ground black pepper

Method

  • Warm the olive oil in a large saucepan over medium-low heat.
  • Add the chopped vegetables, cover and cook gently for about 5 minutes until translucent.
  • Drain the lentils and add to the vegetables.
  • Cook for 3 minutes, stirring.
  • Tie the herbs together with string to make a bouquet garni.
  • Add to the pan along with the vegetable stock.
  • Bring the soup to the boil, reduce the heat and simmer over a medium heat for 1 hour, until the lentils are very soft, skimming away any impurities which rise to the top.
  • Discard the bouquet garni and set aside 4 spoonfuls of lentils as garnish.
  • Puree the soup in a food processor or blender, then push through a fine sieve.
  • Pour it back into the pan, add the vinegar and season to taste.
  • Bring back to the boil.
  • In a separate pan, gently warm the reserved lentils.
  • Stir in the parsley, then spoon the mixture into the centre of individual soup plates.
  • Pour the soup round the edge and drizzle with olive oil.
