Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Carries fat for a rich flavour and smooth mouthfeel, and helps the flour blend evenly.
- Flour
- Its starch swells in the hot liquid and thickens the sauce as it cooks.
- Milk
- Forms the sauce's liquid base, and its milk proteins add body and a creamy texture.
The step that matters
Gradually pour in the hot milk while stirring continuously. Flour starch clumps if liquid is added too fast. Adding the hot milk slowly while stirring separates the starch granules so they swell evenly into a smooth sauce.
Swap the white pepper
How well each one fits the dish's main ingredients (butter, flour, milk):
- Cinnamonfits better
- Nutmegfits better
- Jalapenofits better
- White pepperthe original
Fit is the average pairing score against butter, flour, milk. Candidates are from the same food group and used in at least 100 recipes.
