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

What each ingredient does

Egg yolk
Its proteins set as they heat, thickening the dressing and binding it into a smooth sauce.
Melted butter
Adds richness and a smooth, silky mouthfeel to the dressing.
Cream
Adds moisture and softens the texture, making the dressing lighter and more pourable.
Vinegar
Adds acidity that gives the dressing its sharp, tangy flavour.
Mustard
Adds sharp flavour and helps keep the emulsion stable.

The step that matters

Cooking over boiling water while stirring constantly. Egg yolk proteins thicken the mixture as they warm, but if the heat is too high or stirring stops, the yolk can scramble and turn grainy. Gentle, constant stirring keeps it smooth.
