Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Black beans
- Form the body of the soup, providing starch that thickens the liquid as it cooks down.
- Hard boiled eggs
- Add protein and a soft, creamy texture to the soup.
- Butter
- Adds fat for richness and a smoother mouthfeel.
- Dried thyme
- Contributes a herbal aroma that flavors the broth.
The step that matters
Boil until the beans are thoroughly soft. Dried beans need a sustained boil so their starch fully gelatinises. Undercooked beans stay firm and grainy, so the pulp will not strain into a smooth soup.
Swap the beans
How well each one fits the dish's main ingredients (thyme, egg, butter, pepper):
