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 and add richness as they set during cooking.
Flour
Thickens the liquid into a smooth, stable dressing body.
Butter
Adds fat for a rich, smooth mouthfeel.
Vinegar
Adds acidity for a sharp, tangy flavor.
Milk
Adds liquid and softness to the dressing.

The step that matters

Cook in a double boiler while stirring constantly. Egg yolks can curdle or scramble if overheated. Gentle, constant stirring over indirect heat lets the starch and yolks thicken evenly into a smooth dressing.

Swap the mustard

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