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

What each ingredient does

Onions
Browning in the butter builds deep, savoury flavour as the base of the soup.
Veal or white stock
Forms the liquid base that carries flavour and keeps the vegetables moist during boiling.
Carrots
Add sweetness and body, softening into the broth during the long simmer.
Turnips
Contribute mild sweetness and a firmer texture that holds up to prolonged boiling.
Green peas
Add bright flavour and soft texture to the finished soup.

The step that matters

Browning the onions. Onions must be deeply browned, not just softened, because the Maillard reaction and caramelisation create the savoury colour and flavour that the whole soup depends on. Pale onions give a flat, watery result.

Swap the mace

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

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

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