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

What each ingredient does

Egg yolks
Emulsify with butter to give the dressing its rich, creamy body.
Butter
Adds fat and richness, giving the dressing a smooth, creamy texture.
Sugar
Adds sweetness that balances the sharpness of the vinegar and lemon.
Mustard
Adds sharp flavor and helps stabilise the emulsified dressing.
Vinegar
Adds acidity and thins the dressing to a creamy consistency.

The step that matters

Thin the mixture with vinegar until it reaches a creamy consistency. Adding vinegar too quickly can split the emulsion of yolk and butter. Adding it gradually and stirring keeps the dressing smooth and cohesive.

Swap the lettuce
