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 give it a rich, custard-like body.
Cornstarch
Stabilizes the cooked mixture so it thickens smoothly without curdling.
Egg whites
Add airy lightness when folded in just before serving.
Butter
Adds richness and a smooth, silky mouthfeel.
Vinegar
Adds acidity that gives the dressing its tangy bite.
Sugar
Balances the acidity with sweetness.

The step that matters

Cook in a double boiler, stirring constantly. Egg yolks can scramble if they get too hot or cook unevenly. Gentle indirect heat and constant stirring let the mixture thicken smoothly as the starch and yolk proteins set.

Swap the mustard
