Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Thicken the dressing as they cook and bind it into a smooth, creamy emulsion.
- Butter
- Adds richness and a silky texture to the dressing.
- Made mustard
- Adds sharp flavor and helps stabilize the emulsion.
- Strong vinegar
- Adds acidity that sharpens the flavor and balances the richness of the yolks and butter.
The step that matters
Thickening over boiling water. Egg yolks thicken through gentle heat, but if they get too hot they scramble and turn grainy. Stirring constantly over simmering water keeps the heat even so the dressing becomes smooth.
Swap the celery
The recipe marks celery as optional. How well each one fits the dish's main ingredients (chicken, egg, vinegar, butter, mustard, pepper):
- Tarragonfits better
- Capersfits better
- Dillfits about as well
- Celerythe original
Fit is the average pairing score against chicken, egg, vinegar, butter, mustard, pepper. Candidates are from the same food group and used in at least 100 recipes.
