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, becoming tender and thickening the broth as they cook.
Salt pork
Adds savory fat and meaty flavor to the clear beef broth.

The step that matters

Boiling the beans until tender. Dried beans must be cooked long enough to soften fully; the starches only gelatinize and become digestible after sustained heat, and undercooked beans stay firm and grainy.

Swap the lemon

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

  1. Avocadofits better
  2. Pumpkinfits about as well
  3. Coconutfits about as well
  4. Lemonthe original

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