Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Liver of the fish
- Forms the body of the sauce, giving it a rich, smooth texture when pounded and sieved.
- Flour
- Thickens the pounded liver so the sauce holds together and coats food.
- Broth or melted butter
- Adds moisture and fat, loosening the mixture into a pourable sauce.
- Essence of anchovy, soy, or ketchup
- Adds savoury depth and salt-like seasoning to the sauce.
- Lemon juice
- Adds acidity that brightens the rich flavour of the liver.
The step that matters
Rub through a sieve after boiling. Pounding and sieving breaks the liver into fine particles, which gives a smooth sauce without lumps. Skipping the sieve leaves a grainy texture, and boiling after thickening must be gentle so the flour does not clump.
