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

What each ingredient does

Turnips
Form the body of the soup and, once passed through a sieve, thicken it with their starch and fibre.
Butter
Gently cooks the turnips in fat, carrying flavour without browning them.
Veal or mutton stock
Provides the liquid base and savoury depth for the soup.

The step that matters

Stew the turnips without browning. Over low heat with butter, the turnips should soften gently. If they brown, the Maillard reaction creates bitter, toasted flavours that clash with the mild, sweet soup intended.

Swap the onion

The recipe marks onion as optional. How well each one fits the dish's main ingredients (turnip, butter, veal, white pepper, sugar, cream):

  1. Leekfits better
  2. Parsnipfits about as well
  3. Arrowrootfits about as well
  4. Onionthe original

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