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

What each ingredient does

Butter
Melts into the sauce to add richness and a silky body.
Raw egg yolk
Thickens the sauce as it heats, giving it a smooth, creamy texture.
Anchovies
Adds deep savory flavour that rounds out the sauce.
Lemon or orange juice
Adds acidity that brightens the rich butter and gravy.

The step that matters

Letting the egg yolk boil. Raw egg yolk thickens as its proteins set with heat, but if the sauce boils too hard or too long after the yolk goes in, the yolk can curdle and turn grainy. Keep the heat controlled once the yolk is added.

Swap the onion

How well each one fits the dish's main ingredients (white wine, orange, meat, butter, egg, lemon):
