Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Hard-boiled eggs
- Yolks bind with oil and mustard to form a thick, smooth sauce body.
- Oil
- Adds richness and carries flavour, emulsifying with the yolks into a creamy texture.
- Mustard
- Its natural emulsifiers help hold the oil and yolks together and add sharp flavour.
- Lemon juice
- Adds acidity that brightens the sauce and balances the richness of the oil and yolks.
- Anchovy
- Contributes savoury depth that rounds out the sauce's flavour.
The step that matters
Adding the oil to the yolks. Oil must be incorporated gradually into the yolk mixture so it emulsifies. Adding it too quickly or unevenly can cause it to separate, leaving a greasy, broken sauce.
