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.
