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 into the mixture and give the dressing its body and richness.
Olive oil
Forms the fat base that gives the dressing its thick, creamy texture when emulsified.
Mustard
Helps hold the emulsion together and adds sharpness to the dressing.
Lemon juice
Adds acidity that brightens the flavour and balances the richness of the oil.
Vinegar
Adds acidity that sharpens the flavour and balances the richness of the oil.

The step that matters

Adding the olive oil slowly. Oil must be added gradually while stirring so the yolk can emulsify it into tiny droplets. Adding it too fast can break the mixture so it stays oily and fails to thicken.

Swap the mustard
