Why it works: Parsley and celery match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 6,810 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Oysters
- Main ingredient, cooked gently until plump in the sauce.
- Egg yolks
- Thicken the sauce as they set with gentle heat, giving it a rich texture.
- Butter
- Adds fat and richness, smoothing the flavour and texture of the sauce.
- Flour
- Thickens the milk mixture so the sauce holds together before the yolks are added.
- Milk
- Forms the creamy base of the sauce, adding moisture and mild sweetness.
- Crushed double baked rusk
- Absorbs liquid and adds body to the sauce as it is stirred in.
The step that matters
Stir until the yolks thicken, but do not let it boil. Egg yolks set as they heat, but if the mixture boils they can curdle and turn grainy. Gentle, steady stirring keeps the sauce smooth.
Swap the celery
How well each one fits the dish's main ingredients (oyster, parsley, milk, flour, egg, butter, pepper):
- Nutmegfits better
- Capersfits better
- Thymefits about as well
- Celerythe original
Fit is the average pairing score against oyster, parsley, milk, flour, egg, butter, pepper. Candidates are from the same food group and used in at least 100 recipes.
