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, flavour and pulp of the sauce.
Butter
Carries flavour and enriches the sauce with fat for a smoother mouthfeel.
Flour
Thickens the sauce when cooked with the melted butter, giving it body.
Soup stock
Thins the thickened sauce to the desired consistency and adds savoury depth.

The step that matters

Cook the butter and flour before adding tomato. Cooking the flour in melted butter until it bubbles cooks out its raw starch taste and lets it thicken properly. Adding the tomato too early, or before the roux is cooked, can leave the sauce tasting floury and lumpy.

Swap the tomato

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

  1. Shallotfits better
  2. Carrotfits better
  3. Parsnipfits better
  4. Tomatothe original

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