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

What each ingredient does

Onions
Browning in butter builds the deep, sweet flavour of the soup base.
Flour
Thickens the soup as it fries with the butter and onions.
Turnip
Adds body and a mild, earthy sweetness as it becomes tender.
Carrot
Adds sweetness and soft texture once boiled until tender.
Celery
Adds savoury, aromatic flavour and soft texture once boiled.

The step that matters

Frying the flour with butter. Flour must be cooked in fat until smooth and fully mixed before it goes into the soup. Adding it lumpy or undercooked leaves a pasty taste and uneven thickness, because raw starch does not thicken well until it is hydrated and heated.

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.
