What each ingredient does
- Egg yolks
- Emulsify and thicken the sauce as they set gently with heat.
- Butter
- Adds richness and silky body by emulsifying into the yolk mixture.
- Vinegar
- Adds acidity that sharpens flavour and balances the richness of the butter.
The step that matters
Stir over low heat until thickened. Egg yolks thicken from gentle heat but scramble and curdle if overheated. Keep the heat low and stir constantly so the sauce thickens smoothly.
