Ingredients
Directions
In a saucepan, combine flour and butter, kneading with a wooden spoon.

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 its starch swells when heated.
- Butter
- Cooks with the flour to form a roux that gives the sauce body and richness.
- Milk
- Forms the liquid base that the roux thickens into a creamy sauce.
The step that matters
Stir constantly while boiling. Flour and milk settle and scorch on the bottom of the pan easily. Constant stirring keeps heat even and starch dispersed, so the sauce stays smooth and does not burn.
Swap the white pepper
How well each one fits the dish's main ingredients (flour, butter, onion, parsley, carrot, celery, thyme):
- Marjoramfits better
- Winter savoryfits better
- Tarragonfits better
- White pepperthe original
Fit is the average pairing score against flour, butter, onion, parsley, carrot, celery, thyme. Candidates are from the same food group and used in at least 100 recipes.
