Why it works: Beans and clove match in chemistry and in kitchens. They rank in the top 9% of all ingredient pairs, and cooks put them together in 908 recipes. Both carry 2-heptanol, which smells bitter, floral. The science ↓
Black Bean Soup
Ingredients
Directions
Prepare
Soak the black beans overnight in 3 quarts of cold water.
Cook
In a kettle, combine the soaked beans, 2 quarts of water, and salt pork (or ham bone).
Add the cloves and simmer for 4 to 5 hours until the beans are soft, adding more boiling water as needed.
Pass the mixture through a sieve.
Finish and serve
Add a slice of lemon and the grated yolk of the hard boiled eggs mixed with the egg white to form egg balls.
Stir in sherry wine to taste, if desired.

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 as they soften and break down during long simmering.
- Salt pork
- Adds fat and savory depth to the broth as it simmers with the beans.
- Hard boiled eggs
- Yolks are grated and whites mixed into egg balls as a garnish for the soup.
The step that matters
Simmering until the beans are soft. Dried beans need long, gentle simmering to soften fully; stopping early leaves them firm and the soup grainy. Adding boiling water as needed keeps the level steady without stalling the simmer.
