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

What each ingredient does

Tomato
Provides the main body, acidity and flavour of the sauce.
Butter
Adds fat and richness, and forms a base with the flour.
Flour
Thickens the sauce as its starch swells in the hot liquid.

The step that matters

Add the strained liquid and stir until it thickens. The flour's starch must be cooked in the butter and then hydrated by the liquid. Constant stirring keeps the mixture smooth and lets the starch swell evenly as it heats, so the sauce thickens without lumps.

Swap the clove

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

  1. Garlicfits better
  2. Capersfits better
  3. Thymefits better
  4. Clovethe original

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