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

What each ingredient does

Onions
Caramelise during frying to give the soup its sweetness and deep colour.
Butter
Fat that carries the onion flavour and helps the onions brown.
Flour
Thickens the stock into a smooth, lightly body soup when cooked with the onions.
Stock
Forms the liquid base of the soup and carries the flavour of the vegetables.
Turnip
Adds body and a mild, earthy sweetness as it softens in the soup.
Carrot
Adds sweetness and colour while softening into tender pieces.

The step that matters

Let the onions fry with the flour. Cooking the flour in the onion fat removes its raw taste and lets it thicken the liquid evenly. Stopping too early leaves a pasty flavour and lumps.

Swap the mace

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

  1. Parsleyfits better
  2. Thymefits better
  3. Marjoramfits better
  4. Macethe original

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