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

What each ingredient does

Stewed tomatoes
Provide the main body and tomato flavour of the sauce.
Butter and flour
Melt together to form a roux that thickens the sauce.

The step that matters

Stir constantly until it boils. Flour thickens liquid only as its starch swells with heat and is dispersed evenly. Stirring prevents lumps and scorching on the bottom of the pan.

Swap the mace

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

  1. Thymefits better
  2. Tarragonfits better
  3. Capersfits better
  4. Macethe original

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