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

What each ingredient does

Bread crumb
Soaks up liquid and thickens the soup, giving it body.
White parts of celery, endive, and lettuce
Provide the bulk and mild flavour of the soup, and break down to add body.
Butter
Adds richness and a smooth mouthfeel to the finished soup.
Flour
Thickens the soup with the butter, giving a smoother, slightly fuller texture.

The step that matters

Adding the butter rolled in flour. Flour clumps if dropped straight into hot liquid. Rolling it in butter coats the particles so they disperse, and the soup must be at a boil for the flour to cook and thicken properly.

Swap the onion

How well each one fits the dish's main ingredients (pepper, clove, celery, endive, lettuce, butter, flour):

  1. Turnipfits better
  2. Leekfits better
  3. Beetrootfits better
  4. Onionthe original

Fit is the average pairing score against pepper, clove, celery, endive, lettuce, butter, flour. Candidates are from the same food group and used in at least 100 recipes.
