Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Dried beans
- Form the bulk of the soup and give it body once pressed through a sieve.
- Milk
- Adds creaminess and a soft, rich texture to the soup.
- Butter
- Adds fat and richness, and helps bind the flour into a smooth thickener.
- Flour
- Thickens the soup as it is cooked with the butter and liquid.
The step that matters
Thicken the soup with the blended flour and butter. Flour must be blended smoothly with butter before it goes in, otherwise lumps form. Flour starch thickens only when heated in liquid, so the soup should be kept at a boil briefly to cook out the raw flour taste and reach full thickness.
Swap the onion
How well each one fits the dish's main ingredients (beans, parsley, milk, butter, flour, pepper):
- Shallotfits better
- Potatofits better
- Carrotfits better
- Onionthe original
Fit is the average pairing score against beans, parsley, milk, butter, flour, pepper. Candidates are from the same food group and used in at least 100 recipes.
