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 set during cooking and add richness.
Flour
Stabilises the mixture and helps it thicken smoothly without curdling.
Sugar
Adds sweetness to balance the sharpness of the vinegar.
Vinegar
Adds acidity that gives the dressing its tang.
Butter
Adds fat for a smoother, richer mouthfeel.
Milk
Adds moisture and body, softening the dressing's flavour.

The step that matters

Cook over boiling water, stirring constantly. Egg yolks can scramble if they overheat or sit still. Constant stirring over gentle, indirect heat lets the yolks and starch thicken the dressing evenly into a smooth custard-like texture.

Swap the mustard

How well each one fits the dish's main ingredients (sugar, flour, egg, butter, milk, vinegar):
