Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.

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

What each ingredient does

Milk
Forms the liquid base of the sauce and supplies the body that thickens as it heats.
Butter
Carries flavour and fat, and coats the flour so it blends smoothly without lumps.
Flour
Thickens the sauce by absorbing liquid and swelling as it heats with the milk.

The step that matters

Adding the milk to the roux. Flour and melted butter form a roux that must be combined smoothly before the milk goes in. Adding milk gradually and stirring keeps starch granules dispersed, which prevents lumps as the sauce thickens on heating.

Swap the celery

The recipe marks celery as optional. How well each one fits the dish's main ingredients (milk, butter, flour, white pepper, pepper, lemon):

  1. Parsleyfits better
  2. Nutmegfits better
  3. Cardamomfits better
  4. Celerythe original

Fit is the average pairing score against milk, butter, flour, white pepper, pepper, lemon. Candidates are from the same food group and used in at least 100 recipes.
