This to me is the best possible sauce for any sort of fish. Due to the reducing, it’s very intense, creamy and utterly out of this world. (When I made this for my step-daughter several years ago, she literally was brought to tears)

This amount serves 2 – 4, depending on how much sauce you want!
* Sometimes I use 4 fl oz of Noilly Prat instead of white wine, which makes it more intense)

8 fl oz good fish stock
4 fl oz dry white wine
3 tbsp Noilly Prat
2 small shallots, finely chopped
1/2 pint heavy cream
1 1/2 oz butter, chilled & cut into small cubes
2 tbsp fresh chives, finely cut
Salt and pepper

Put the fish stock, wine, Noilly Prat and chopped shallot in a pan and boil rapidly, reducing until 1/4 of the volume is left.

Add the cream and boil gently, stirring constantly, to reduce to the required consistency and taste. (The consistency is right when it thickly coats the back of a spoon and tastes intense)
When it’s to your liking, remove from the heat and whisk in the butter cubes one by one.
Strain through a fine sieve and season.

You can also liquidize the sauce before adding the chives to make it extra light and fluffy, or if you prefer it as is, add the chives just before you serve it.
