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

What each ingredient does

Stewed strained tomatoes
Provide the liquid base and the main tomato flavor of the sauce.
Flour
Thickens the sauce by swelling in the hot liquid as it cooks.
Butter
Adds fat and a rich, smooth mouthfeel to the sauce.

The step that matters

Make a smooth paste with the flour and butter. Stirring flour into melted butter before adding liquid coats the starch granules so they disperse evenly. Without this, the flour can clump, leaving lumps in the finished sauce.

Swap the tomato

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

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

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