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

What each ingredient does

Crumb of a small baker's loaf
Bread crumb soaks up liquid and thickens the soup body.
White parts of celery, endive, and lettuce
Vegetables give the soup its body and mild, fresh flavour.
1 lump of butter
Butter rolled in flour enriches the soup and helps it thicken smoothly.
1 tablespoon flour
Flour coating the butter helps thicken the soup without lumps.

The step that matters

Adding the butter rolled in flour. Flour needs to be whisked or dispersed into hot liquid and boiled briefly to thicken without lumps. Dropping it in unevenly can leave clumps, so it should be added once the soup is already boiling.

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.
