Method
- For the fish bone broth: Prepare a large saucepan. Place the fish bones in the saucepan. Cut the lemon in half, roughly chop the celery, and cut the onion into quarters. Add the lemon, celery, onion, bay leaf, parsley, salt, and peppercorns to the saucepan.
- Pour in the 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 large bowl or jug. Let it settle and 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 cook until softened.
- Pour in the champagne and bring to a gentle boil. Reduce the volume by one-third.
- Add the fish stock and cream. Bring back to a boil and reduce by half.
- Season the sauce with salt and pepper.
- Strain the sauce through a sieve to remove the shallot. Return the sauce to the pan and heat gently until just below simmering point.
- Turn off the heat. Whisk in a few extra cubes of cold butter until the sauce is smooth and glossy. Serve immediately.

Notes
