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

What each ingredient does

Eggs
Coagulate when gently heated, thickening the dressing into a custard-like texture.
Cream
Adds richness and moisture, softening the sharpness of the vinegar.
Butter
Adds fat for a smooth, rounded mouthfeel in the finished dressing.
Vinegar
Provides acidity that gives the dressing its tangy flavour.
Mustard
Adds sharp flavour and helps emulsify the eggs and fat.

The step that matters

Cook while stirring constantly. Egg proteins set gently with heat, so the mixture can curdle if it overheats or stops being stirred. Slow, constant stirring over a double boiler keeps it smooth and thickens it evenly into soft custard.
