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

What each ingredient does

Oysters
Provide the main flavour and texture of the soup.
Butter
Adds richness and fat, carrying flavour through the broth.
Flour
Thickens the soup as it cooks with the butter.
Cream
Adds richness and a smoother, mellower body to the soup.
Bacon
Adds smoky, savoury fat that flavours the broth.

The step that matters

Add the butter rolled in flour near the end. Flour thickens only when heated in liquid long enough to swell its starch. Adding the butter-flour ball near the end and letting it simmer lets it dissolve evenly without lumps, while the cream added then stays fresh and does not curdle from long boiling.

Fit is the average pairing score against oyster, parsley, thyme, pepper, butter, flour, cream. 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).
