Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Liver
- Provides the main savory body and rich flavour of the sauce.
- Parsley
- Adds fresh, herbal aroma and a green note that cuts the richness.
- Butter
- Carries the flavours and gives the sauce a smooth, rich mouthfeel.
The step that matters
Blanching the parsley and liver separately. Blanching briefly in boiling water softens the parsley and firms the liver so they can be minced cleanly. Blanching too long can dull the parsley's bright green colour and make the liver tough, so timing matters.
