Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Liver of fish
- Forms the body of the sauce, giving it a rich, smooth texture when pounded.
- A little flour
- Helps bind the pounded liver so it thickens the liquor into a sauce.
- Liquor from boiled fish
- Serves as the flavourful liquid base that the liver is stirred into.
- Catsup or soy sauce
- Adds savoury depth and salt-like seasoning to the sauce.
- Squeeze of lemon juice
- Adds acidity that brightens the rich fish flavour.
The step that matters
Pound the liver with the flour before stirring it into the liquor. Pounding breaks the liver into a fine paste and mixing it with flour first helps it disperse evenly, so the sauce avoids lumps and thickens smoothly.
