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

What each ingredient does

Onions
Browned in butter, they build the deep, sweet flavour base of the soup.
Flour
Cooked with butter, it thickens the soup and gives it body.
Butter
Fat that browns the onions and carries flavour through the soup.
Turnip
Cut into fillets and cooked until tender, adding mild body and vegetable flavour.
Carrot
Cooked until tender, adding sweetness and colour to the soup.

The step that matters

Frying the flour into the onions. Flour must be mixed smooth with butter before it goes in, and it needs time to cook; otherwise it stays lumpy and tastes raw. Cooking it briefly in fat develops flavour and lets it thicken the liquid evenly.

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.
