Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lima beans
- Form the main body of the soup and give it its starchy, substantial texture.
- Butter
- Carries the onion's flavor and adds richness to the soup.
- Flour
- Thickens the soup as it browns and cooks with the butter.
- Milk
- Adds creaminess and a smooth, mellow body to the finished soup.
- Onion
- Browning in butter builds sweetness and savory aroma.
The step that matters
Browning the flour. Stirring the flour in butter until smooth and brown cooks out its raw taste and builds nutty flavor. It scorches quickly and can turn bitter, so keep it moving over the heat.
Swap the onion
How well each one fits the dish's main ingredients (lima beans, butter, milk, flour):
- Potatofits better
- Okrafits better
- Asparagusfits better
- Onionthe original
Fit is the average pairing score against lima beans, butter, milk, flour. Candidates are from the same food group and used in at least 100 recipes.
