- For the fish bone broth: Place fish bones in a large saucepan. Add quartered onion, roughly chopped celery, halved lemon, bay leaf, parsley, salt, and peppercorns.
- Pour in water and champagne. Bring to a simmer and cook for 30 minutes.
- Remove from heat. Strain the broth through a sieve lined with muslin cloth into a bowl or jug. Let it settle, then skim off any residue from the top.
- For the champagne cream sauce: Finely dice the shallot.
- Heat butter in a saucepan over medium heat. Add the shallot and gently fry until softened.
- Pour in the champagne and bring to a gentle boil. Reduce the liquid by one-third.
- Add the fish stock and cream. Bring back to a boil and reduce the liquid by half.
- Season the sauce with salt and pepper.
- Sieve the sauce to remove the shallot. Return the sauce to the pan and heat gently until just below simmering point.
- Turn off the heat and whisk in a few extra cubes of cold butter until the sauce is smooth and glossy. Serve immediately.

Notes
This sauce is best served immediately after preparation to maintain its glossy finish.
