Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Emulsify the butter and oil, giving the sauce a smooth, thick body.
- Unsalted butter
- Adds richness and a creamy, silky texture to the sauce.
- Olive oil
- Adds fat and helps hold the emulsion together for a smooth finish.
- Anchovies
- Contribute a deep, savoury saltiness that rounds out the sauce.
- Gherkins
- Add acidity and a crisp tang that cuts through the rich fats.
- Capers
- Add a sharp, briny acidity that brightens the sauce.
The step that matters
Adding the butter and oil to the paste. Fats must be added gradually and mixed well so they emulsify with the egg yolk paste. Adding them too fast can cause the sauce to separate and turn greasy instead of smooth.
Swap the mustard
