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

What each ingredient does

Egg yolks
Form the creamy base that emulsifies the dressing and gives it body.
Thick cream
Adds richness and moisture, softening the dressing's texture.
Tarragon vinegar
Adds acidity that brightens the dressing and balances the richness.
Mixed mustard
Contributes sharpness and helps bind the emulsion.
Sardines
Supply savory, salty flavour and fish character to the dressing.

The step that matters

Gradually mix in the cream, tarragon vinegar, and lemon juice. Adding liquids slowly lets the mashed yolks absorb them and form a stable, smooth emulsion. Dumping them in together can cause the dressing to separate or stay lumpy.

Swap the white pepper
