Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Dried beans
Form the body of the soup and thicken it as they break down during long boiling.
Salt pork
Adds savory, fatty flavor that seasons the broth as it simmers.
Butter or drippings
Carries the flour and adds rich fat flavor to the thickening roux.
Flour
Thickens the soup once cooked in fat into a roux and stirred in.

The step that matters

Cook the flour mixture until light brown. Cooking flour in fat develops a nutty flavor and removes raw starch taste; stopping too early leaves a pasty taste, while overcooking scorches it and makes it bitter.

Swap the onion

How well each one fits the dish's main ingredients (beans, pork, pepper, butter, flour):

  1. Potatofits better
  2. Capsicumfits better
  3. Asparagusfits better
  4. Onionthe original

Fit is the average pairing score against beans, pork, pepper, butter, flour. Candidates are from the same food group and used in at least 100 recipes.
