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

What each ingredient does

Butter
Carries the aromatics and adds richness and a rounded flavor to the sauce.
Onion
Softens into sweetness and builds the base aroma as it simmers.
Flour
Thickens the sauce as its starch swells in the hot fat and liquid.
Sieved tomatoes
Provide the main liquid, body, and bright acidity of the sauce.

The step that matters

Stirring the flour until smooth but not browned. Flour must cook in the fat long enough to lose its raw taste and thicken the sauce. Letting it brown changes the color and flavor, and too much heat can scorch it, so keep the heat moderate and stir constantly.

Swap the white pepper

How well each one fits the dish's main ingredients (butter, onion, pepper, flour, tomato):

  1. Garlicfits better
  2. Thymefits better
  3. Parsleyfits better
  4. White pepperthe original

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