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, flavor, and pulp that forms the sauce.
Butter
Adds richness and fat that carries flavor in the sauce.
Flour
Thickens the sauce as it cooks with the butter, giving it body.

The step that matters

Cooking the butter and flour together. The flour must cook in the melted butter until well mixed so it thickens smoothly and loses its raw taste. Adding the tomato pulp before this roux is fully combined can leave lumps and a floury flavor.

Swap the onion

The recipe marks onion as optional. How well each one fits the dish's main ingredients (tomato, clove, parsley, pepper, butter, flour):

  1. Carrotfits better
  2. Capsicumfits better
  3. Shallotfits better
  4. Onionthe original

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