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.
