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

What each ingredient does

Egg yolks
Thicken the dressing as they cook and set, giving it a smooth, creamy body.
Butter
Adds richness and a silky mouthfeel to the dressing.
Vinegar
Adds acidity that sharpens the flavor and balances the sweetness.
Sugar
Adds sweetness that balances the sharpness of the vinegar and mustard.
Mustard
Adds sharp, pungent flavor and helps emulsify the dressing.

The step that matters

Cook over boiling water until thick. Egg yolks thicken as their proteins set with gentle heat. If the heat is too high or cooking goes on too long, the yolks can scramble and curdle, so the dressing should be stirred and cooked gently over simmering, not boiling, water.

Swap the mustard
