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 over gentle heat, giving it a rich, creamy body.
Egg whites
Whipped to stiff peaks, they lighten the dressing and add airy volume.
Vinegar
Adds acidity that sharpens the flavour and balances the richness of the yolks and fat.
Cream or milk
Adds moisture and softness, mellowing the dressing into a smoother texture.
Butter or oil
Adds fat that makes the dressing feel smooth and rounded on the palate.

The step that matters

Cooking the yolk mixture in the double boiler. Egg yolks thicken as their proteins set, but if the heat is too high they scramble and curdle. Gentle, indirect heat keeps the mixture smooth while it thickens.

Swap the mustard

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