Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Thickens the milk into a smooth sauce as it cooks.
- Butter
- Adds richness and helps the flour blend smoothly into the sauce.
- Milk
- Forms the liquid base that the flour and butter thicken.
- Celery
- Provides the main flavor and body of the sauce.
The step that matters
Stirring the flour and butter into boiling milk. Adding the roux to hot milk while stirring constantly keeps it from clumping. Lumps form when starch hits hot liquid unevenly, so the sauce thickens smoothly only with steady stirring.
Swap the celery
How well each one fits the dish's main ingredients (flour, butter, milk):
- Cinnamonfits better
- Nutmegfits better
- Jalapenofits better
- Celerythe original
Fit is the average pairing score against flour, butter, milk. Candidates are from the same food group and used in at least 100 recipes.
