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
