Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Livers
Provide the main body and savory flavor of the sauce when pounded smooth.
Egg yolks
Emulsify the butter and help bind the sauce into a smooth, thick texture.
Butter
Adds richness and fat, giving the sauce a silky mouthfeel as it thickens.
Egg white
Adds body and helps thicken the sauce as it is heated.
Anchovies
Add salty, savory depth that enhances the flavor of the livers.
Lemon juice
Adds acidity that brightens the rich livers and butter.

The step that matters

Stirring the sauce as it thickens. Constant stirring over gentle heat keeps the egg proteins from overheating and curdling, which would leave the sauce grainy instead of smooth.

Swap the thyme

How well each one fits the dish's main ingredients (liver, parsley, pepper, lemon, egg, butter):
