Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds richness and body, emulsifying into the liquid to give the sauce a smooth, glossy texture.
- Raw egg yolk
- Thickens the sauce as its proteins set with gentle heat, adding richness and smoothness.
- Meat or fish gravy
- Provides the savoury liquid base that carries the other flavours.
- Anchovies
- Contributes deep savoury flavour that enriches the sauce without tasting distinctly fishy.
- Lemon or orange juice
- Adds acidity that brightens the rich butter and balances the sauce.
The step that matters
Adding the raw egg yolk. Egg yolk thickens when its proteins set with heat, but if it boils too hard or too long it can curdle and turn grainy. Keeping the sauce at a gentle boil only briefly protects its smooth texture.
