Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Shelled beans
- Form the main body of the stew and absorb the cooking liquid as they soften.
- Salt pork
- Renders fat into the pot, adding richness and savory flavor to the stew.
- Onion
- Softens and sweetens as it cooks, building a flavor base for the stew.
- Flour
- Stirred into the beans, it helps thicken the stewing liquid.
The step that matters
Simmering the beans for 2 hours. A long, gentle simmer lets the beans soften fully and the liquid thicken. Too hard a boil can break the beans apart and make the stew cloudy.
Swap the onion
How well each one fits the dish's main ingredients (beans, pork, pepper, flour):
- Okrafits better
- Capsicumfits better
- Spinachfits better
- Onionthe original
Fit is the average pairing score against beans, pork, pepper, flour. Candidates are from the same food group and used in at least 100 recipes.
