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

What each ingredient does

Turnips
Provide the main body and mild sweetness of the soup as they stew until tender.
Cream
Adds richness and a smooth, creamy texture to the soup.
Flour
Mixed with the cream, it thickens the soup when boiled with it.
Roll
Soaks up the broth, giving the dish a soft, bread-thickened body.

The step that matters

Boil the flour and cream mixture with the soup. Flour thickens only when heated, and it can clump if added directly. Mixing it with cream first and then stirring it into the simmering soup helps it disperse smoothly and thicken evenly.

Swap the white pepper

How well each one fits the dish's main ingredients (turnip, mace, cream, flour):

  1. Nutmegfits better
  2. Capersfits better
  3. Marjoramfits better
  4. White pepperthe original

Fit is the average pairing score against turnip, mace, cream, flour. Candidates are from the same food group and used in at least 100 recipes.
