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):
- Turnipfits better
- Leekfits better
- Beetrootfits better
- 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.
