Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Liver
- Forms the body of the sauce, giving it a rich, savory base once pounded and boiled.
- Butter
- Adds fat and smoothness, carrying flavor and giving the sauce a silky texture.
- Lemon juice
- Adds acidity that brightens the rich liver and balances its heaviness.
- Anchovy
- Adds deep savory saltiness and umami if used, rounding out the sauce.
The step that matters
Boil the pounded liver with melted butter. Boiling too hard or too long can toughen and grain the liver proteins and cause the butter to separate, leaving a gritty, greasy sauce. Keep the heat gentle and stir until the mixture is smooth and evenly combined.
