Make the most of any leftover langoustine shells with this delicate creamy soup. It also works well with lobster shells.
Equipment and preparation: for this recipe you will need a blender strong enough to break down the langoustine shells.
Heat the butter in a frying pan and gently fry the shallot and garlic until the shallot is translucent. Add the tomato purée and cook for a further two minutes, then add the carrot, langoustine shells, brandy, stock and cream. Cook for 3-4 minutes.
Place the mixture into a sturdy blender and pulse for two minutes until smooth. Pass through a fine sieve into a clean pan. Season, to taste, with salt and pepper.
Serve in bowls topped with the croutons and spring onion.
