Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Thicken the vinegar mixture into a custard and emulsify the dressing.
- Vinegar
- Provides acidity that sharpens the flavour and helps set the custard.
- Cream
- Adds richness and a smooth, creamy body to the dressing.
- Mustard
- Adds sharp flavour and helps stabilise the emulsion.
- Butter
- Adds fat and a rounded richness to the cooked vinegar base.
The step that matters
Return the mixture to the heat and stir until it thickens like custard.. Egg yolks thicken when gently heated, but if they get too hot they scramble into lumps. Keep the heat low and stir constantly, removing the pan once it coats a spoon.
Swap the celery
How well each one fits the dish's main ingredients (vinegar, egg, butter, cream, mustard, sugar):
- Tarragonfits better
- Capersfits better
- Nutmegfits better
- Celerythe original
Fit is the average pairing score against vinegar, egg, butter, cream, mustard, sugar. Candidates are from the same food group and used in at least 100 recipes.
