Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Celery
- Provides the main flavour and the bulk of the sauce once boiled and sieved.
- Egg yolk
- Enriches the sauce and helps it set into a smooth, creamy texture.
- Butter
- Adds richness and a silky mouthfeel to the finished sauce.
- Flour
- Thickens the sauce slightly if used, giving it more body.
The step that matters
Mix in the beaten egg yolk and lemon juice. Egg yolk thickens when heated gently, but if the sauce is too hot when it goes in, the yolk can scramble and turn grainy. Adding it off the heat or with the sauce only warm keeps it smooth.
Swap the celery
How well each one fits the dish's main ingredients (egg, lemon, butter, pepper, flour):
- Parsleyfits better
- Tarragonfits better
- Nutmegfits better
- Celerythe original
Fit is the average pairing score against egg, lemon, butter, pepper, flour. Candidates are from the same food group and used in at least 100 recipes.
