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

What each ingredient does

Egg yolks
Emulsify the oil and thicken the dressing as they set with heat.
Olive oil
Adds fat and richness, giving the dressing a smooth body.
Flour
Thickens the liquid so the dressing becomes spoonable rather than runny.
Vinegar
Provides the sharp acidity that defines the dressing's flavor.
Sugar
Balances the acidity of the vinegar with a touch of sweetness.

The step that matters

Return the mixture to the saucepan and bring to a boil, stirring constantly.. Egg yolks can scramble if overheated or left unstirred. Constant stirring keeps heat even, and the starch from the flour thickens the dressing as it cooks.

Swap the mustard
