Ingredients

  • 1 bunch watercress
  • 1/2 md. onion, coarsely chopped
  • 1 md. potato, roughly diced
  • 1/2 clove garlic, chopped
  • 1/2 oz. butter
  • 3 cups water
  • 1 tbsp. heavy cream
  • 1 oz. black caviar
  • 4 water biscuits
  • 1 dash salt and pepper, to taste

Method

  • Gently fry onion and garlic in a small amount of butter until transparent.
  • Season lightly with salt and pepper; and add water and potato and boil until soft.
  • Pick over watercress and chop 4 or five sprigs and set them aside.
  • Put onion and potato mixture in blender and puree.
  • Add most of watercress; blend.
  • Re-season to taste and return to heat.
  • Bring mixture to boil and simmer for 2 or three minutes.
  • Stir gently to prevent soup from sticking to bottom.
  • Remove from heat.
  • This is the decision point.
  • Either set aside to cool, then chill, or carry on to serve the soup hot.
  • Stir in cream and chopped watercress.
  • Heap a teaspoon of caviar on each of the water biscuits and float one on each bowl of soup immediately prior to serving.
