Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Egg yolks
Emulsify the oil and thicken the mixture as they cook, giving a rich, stable body.
Whole eggs
Add structure and help the mixture thicken when gently heated.
Olive oil
Supplies the fat that forms the creamy, smooth body of the sauce.
Cream
Adds moisture and softness, and can be added to loosen the texture.
Vinegar
Adds acidity that brightens the flavour and balances the richness of the fat.
Lemon juice
Adds acidity that brightens the flavour and balances the richness of the fat.

The step that matters

Cook over boiling water while stirring constantly. The egg proteins thicken as they heat, but overheating can scramble them into lumps. Constant stirring spreads heat evenly so the sauce thickens smoothly.
