Why it works: Lemon and pepper match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 27,047 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Celery
- Forms the body of the sauce and gives it its main flavour.
- Egg yolk
- Enriches the sauce and helps it set smoothly when gently heated.
- Butter
- Adds fat for a rich, smooth mouthfeel.
- Lemon juice
- Adds acidity that brightens the celery flavour and balances richness.
- Flour
- Thickens the sauce so it holds more body, if used.
The step that matters
Mix in the egg yolk. Egg yolk can curdle or scramble if the sauce is too hot when it is added. Mixing it in gently, off direct heat, keeps the sauce 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.
