Why it works: Pepper and celery match in chemistry and in kitchens. They rank in the top 5% of all ingredient pairs, and cooks put them together in 16,012 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Enriches the sauce and carries flavour while helping form a smooth base with the flour.
- Flour
- Thickens the liquid into a smooth, pourable sauce once cooked into a paste.
- Oyster liquor
- Provides the main briny flavour and forms the liquid base of the sauce.
- Cream or milk
- Adds richness and body, giving the finished sauce a smooth, glossy texture.
- Oysters
- Serve as the main ingredient, bringing the sauce's characteristic flavour and texture.
The step that matters
Adding the hot liquor to the paste. Pouring the liquor in slowly while beating constantly keeps the flour evenly dispersed, so the sauce thickens smooth rather than lumpy.
Swap the celery
How well each one fits the dish's main ingredients (butter, cream, flour, oyster, pepper):
- Nutmegfits better
- Parsleyfits about as well
- Capersfits about as well
- Celerythe original
Fit is the average pairing score against butter, cream, flour, oyster, pepper. Candidates are from the same food group and used in at least 100 recipes.
