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, acidity and flavour of the soup.
Stock
Forms the liquid base that carries the soup's flavour.
Semolina
Thickens the soup as it heats, giving it body.
Carrot
Adds sweetness and body once simmered and pressed through.
Turnip
Adds body and mild earthy flavour once simmered and pressed through.

The step that matters

Stir the semolina in gently. Semolina thickens as its starch gelatinises in hot liquid. Adding it to a boiling soup or stirring vigorously can cause lumps or a gummy texture, so it should be sprinkled in while the soup is hot but not violently boiling, and stirred gently.

Swap the mace

How well each one fits the dish's main ingredients (tomato, carrot, turnip, shallot, vinegar, semolina, pepper):

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

Fit is the average pairing score against tomato, carrot, turnip, shallot, vinegar, semolina, pepper. Candidates are from the same food group and used in at least 100 recipes.
