Directions

Pound it in a mortar with a little flour.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Liver of the fish
- Provides the main body and rich flavour that thickens the sauce when pounded and sieved.
- Flour
- Thickens the sauce and gives it body when pounded with the liver.
- Broth or fish liquor
- Supplies liquid to loosen the mixture into a pourable sauce.
- Melted butter
- Adds fat for smoothness and a rich, silky mouthfeel.
- Essence of anchovy
- Adds savoury, salty depth that rounds out the fish flavour.
The step that matters
Rub through a sieve after boiling. Pounding the liver with flour and then rubbing the sauce through a sieve removes lumps and fibres, so the sauce turns smooth rather than grainy. Bringing it to a boil thickens the flour starch so the sauce holds together.
