Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Oysters
- Provide the main flavor and body of the soup once pressed into the sauce.
- Milk
- Forms the liquid base of the soup and carries the flavors.
- Butter
- Adds richness and fat, helping the flour blend smoothly into the sauce.
- Flour
- Thickens the milk into a creamy sauce when cooked with the butter.
The step that matters
Stir until the mixture thickens. Flour must be stirred with the butter and hot milk so starch granules swell evenly; stirring prevents lumps and gives a smooth, properly thickened base.
Swap the celery
How well each one fits the dish's main ingredients (oyster, milk, butter, flour, onion):
- Capersfits better
- Garlicfits about as well
- Nutmegfits about as well
- Celerythe original
Fit is the average pairing score against oyster, milk, butter, flour, onion. Candidates are from the same food group and used in at least 100 recipes.
