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 flavour and rich body of the sauce.
- Lemon
- Adds acidity and fragrant aroma from the rind and juice.
- Butter
- Adds fat and richness, giving the sauce a smooth, flowing texture.
The step that matters
Heat gradually without boiling. Boiling can make melted butter separate and make the liver turn tough or grainy. Gentle, gradual heat keeps the sauce smooth and the liver tender.
