Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

White sauce: Forms the creamy base that carries the other flavours and holds the oysters.
Oysters: Supply the main savoury, briny flavour of the sauce.
Grated onion: Adds a sharp, aromatic note that deepens the savoury flavour.
Chopped celery: Adds a fresh, slightly bitter vegetable crunch and aroma.

Fit is the average pairing score against sauce, onion, oyster. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
