Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Liver of the fish
Breaks down into a rich, thick body that gives the sauce its main flavour and texture.
Flour
Thickens the liver mixture so it binds into a smooth sauce.
Broth or cooking liquid from the fish
Provides the liquid base that loosens the thickened mixture into a pourable sauce.
Melted butter
Adds fat for a silky mouthfeel and rounded flavour.
Lemon juice or diced lemon
Adds acidity that brightens the rich liver flavour.

The step that matters

Bring to a boil and strain through a sieve. Boiling thickens the flour-starch mixture fully, while straining removes lumps and fibrous bits so the sauce turns smooth. Stop once it is thick enough to coat a spoon.
