Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Navy beans
- Form the main body of the soup and thicken it when pressed through a sieve.
- Salt pork or bacon
- Adds fat and savory depth that carries through the whole soup.
- Baking soda
- Raises the cooking water's alkalinity, helping the bean skins soften.
- Tomatoes
- Add acidity and a bright flavor that balances the richness of the pork.
- Onions
- Build sweetness and aroma as the base flavor of the soup.
- Milk or cream
- Adds fat and smoothness, softening the texture when thinning the soup.
The step that matters
Boil gently until the beans are soft. A hard boil breaks beans apart and clouds the broth, while gentle heat lets them soften evenly so they press smoothly through the sieve.
Swap the clove
How well each one fits the dish's main ingredients (beans, pork, tomato, onion, garlic, carrot, celery):
- Cuminfits better
- Thymefits better
- Parsleyfits better
- Clovethe original
Fit is the average pairing score against beans, pork, tomato, onion, garlic, carrot, celery. Candidates are from the same food group and used in at least 100 recipes.
