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

What each ingredient does

Tomatoes
Provide the main flavour and body of the soup, breaking down during cooking.
Butter
Adds richness and fat, carrying flavour through the soup.
Flour
Thickens the milk mixture so it lends body to the soup.
Milk
Adds creaminess and softens the soup's flavour.
Crushed tapioca
Thickens the soup further when stirred in near the end.

The step that matters

Stir the flour-milk mixture in while the soup is hot. Adding flour to liquid without first making a paste can cause lumps. Stirring constantly as the soup heats lets the starch disperse and thicken evenly, and the soup must then be brought to a boil to fully thicken.

Flavor stand-ins for the mace

How well each one fits the dish's main ingredients (tomato, fish, flour, butter, milk, onion, clove):

  1. Cinnamonbetter flavor fit
  2. Cardamombetter flavor fit
  3. Thymebetter flavor fit
  4. Macethe original

Fit is the average pairing score against tomato, fish, flour, butter, milk, onion, clove. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
