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

What each ingredient does

Tomatoes
Provide the main body, acidity and flavour of the sauce.
Butter
Adds fat and richness to the sauce, rounding out its texture.
Flour
Thickens the sauce as it cooks, giving it body and a smoother consistency.
Sugar
Balances the acidity of the tomatoes, softening the sharp taste.

The step that matters

Adding the butter rolled in flour. Flour clumps easily if dropped in loose. Rolling the butter in flour first lets it disperse into the hot sauce, so it thickens smoothly instead of forming lumps.

Swap the tomato

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

  1. Capsicumfits better
  2. Arrowrootfits better
  3. Shallotfits better
  4. Tomatothe original

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