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

What each ingredient does

Egg yolks
Emulsify with the cream to give the dressing a smooth, thick body without oil.
Cream
Adds richness and moisture, loosening the yolk paste into a pourable dressing.
Mustard
Adds sharpness and helps bind the emulsion together.
Bacon
Adds savory fat and salt, with crisp texture from frying.
Vinegar
Adds acidity that brightens the dressing and cuts the richness of the cream and bacon fat.

The step that matters

Gradually stir in the cream. Adding cream slowly to the yolk paste lets the mixture combine smoothly. Adding it all at once can leave lumps or a thin, separated dressing.

Swap the lettuce

How well each one fits the dish's main ingredients (egg, mustard, pepper, cream, tarragon, vinegar):
