Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beans
- Form the body of the soup and provide most of its substance.
- Graham flour or oatmeal
- Thickens the broth as it heats, giving the soup more body.
- Spinach
- Adds soft texture and a mild, earthy flavor once scalded.
- Parsley
- Adds fresh, herbal aroma and a light green flavor.
The step that matters
Stirring in the flour or oatmeal. Flour or oatmeal can clump if dropped in without stirring. Stirring while the liquid heats helps the starch disperse and thicken evenly as it boils.
Swap the kidney beans
How well each one fits the dish's main ingredients (flour, spinach, parsley):
- Chickpeafits better
- Lentilsfits better
- Cashew nutfits better
- Kidney beansthe original
Fit is the average pairing score against flour, spinach, parsley. Candidates are from the same food group and used in at least 100 recipes.
