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

What each ingredient does

Egg
Thickens the dressing as it cooks and gives it body and richness.
Butter
Adds fat for a smooth, rich mouthfeel in the dressing.
Cream or rich milk
Adds fat and moisture, making the dressing creamy and mellow.
Flour
Helps thicken the dressing and keeps it from splitting as it heats.
Vinegar
Adds acidity that gives the dressing its tangy flavour.
Sugar
Balances the sharpness of the vinegar with a touch of sweetness.

The step that matters

Adding the vinegar slowly. Pouring vinegar in quickly can curdle the egg and cause a lumpy dressing. Adding it slowly while mixing lets the egg blend in evenly, so the dressing cooks smooth.

Swap the mustard

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