Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Thicken the sauce and give it a rich, smooth body as they gently set with heat.
- Butter
- Adds fat and richness, helping the sauce feel smooth and silky on the palate.
- Vinegar
- Adds acidity that sharpens the flavour and balances the richness of the yolks and butter.
- Grated horseradish
- Provides the pungent, sharp heat that defines the sauce's flavour.
The step that matters
Heat gently without boiling. Egg yolks thicken through gentle heat, but if they get too hot they can scramble and curdle, leaving the sauce grainy instead of smooth.
