Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Canned peas
- Provide the main body and flavor of the soup once pureed.
- Milk
- Forms the liquid base of the soup and adds creaminess.
- Butter
- Adds fat and richness, helping carry flavor through the soup.
- Flour
- Thickens the soup as it cooks with the butter and liquid.
The step that matters
Adding the butter and flour mixture to the boiling soup. Flour must be fully blended with the butter before it goes in, and the soup should be stirred well as it thickens. Otherwise lumps can form and the starch will not thicken the soup evenly.
Swap the peas
How well each one fits the dish's main ingredients (milk, butter, flour, onion, pepper):
- Almondfits better
- Beansfits better
- Chestnutfits better
- Peasthe original
Fit is the average pairing score against milk, butter, flour, onion, pepper. Candidates are from the same food group and used in at least 100 recipes.
