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 a creamy, emulsified body.
Butter
Adds richness and a smooth mouthfeel to the dressing.
Cream
Adds body and softness, mellowing the sharpness of the vinegar.
Vinegar
Provides the acidity that gives the dressing its tang.
Sugar
Balances the acidity of the vinegar with a touch of sweetness.

The step that matters

Cook over boiling water while stirring constantly. Egg proteins set gradually as they heat. Stirring constantly and keeping the heat gentle spreads the heat evenly and prevents scrambling, giving a smooth, thickened dressing.

Swap the mustard

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