Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Thicken the sauce and help hold the butter in a smooth emulsion.
- Butter
- Adds richness and a silky, smooth texture to the sauce.
- White sauce
- Gives the sauce body and a thicker base for the eggs and butter.
- Vinegar
- Adds acidity that sharpens the flavour and balances the richness.
- Lemon juice
- Adds brightness and acidity that cuts through the butter.
The step that matters
Adding the remaining butter gradually. Egg yolks bind with fat only when butter is added slowly and the mixture stays warm but not hot. Adding butter too fast or overheating can break the sauce, leaving it oily or scrambled.
Swap the lemon
