Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Black beans
- Softened and pureed into the pulp that forms the body and thick texture of the soup.
- Dried thyme
- Adds herbal aroma as its flavor is released into the simmering broth.
- Hard boiled eggs
- Add mild richness and substance as sliced pieces in the soup.
- Butter
- Adds fat for a rounder mouthfeel and richer flavor.
The step that matters
Boil the beans until thoroughly soft. Beans that are undercooked stay firm and grainy and will not break down into a smooth pulp. Full softening lets the starches release and the pulp thicken the soup, so the cook should keep boiling until the beans mash easily before straining.
Swap the beans
How well each one fits the dish's main ingredients (thyme, egg, butter, pepper):

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