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 butter, giving the dressing its thick, creamy body.
Melted butter
Adds richness and fat, making the dressing smooth and mellow.
Olive oil
Adds fat that forms the emulsion and carries flavor.
Vinegar
Adds acidity that sharpens the flavor and balances the richness.
Mustard
Helps stabilize the emulsion and adds sharp flavor.
Whipped cream
Lightens the dressing and adds moisture and softness when added at serving.

The step that matters

Stir constantly in an earthen dish to prevent separation.. The dressing is an emulsion of fat and water-based liquids held together by egg yolk. Without constant stirring while the fats are added, the mixture can break and separate into oily and watery layers.

Swap the mustard
