Why it works: Pepper and clove match in chemistry and in kitchens. They rank in the top 5% of all ingredient pairs, and cooks put them together in 17,451 recipes. Both carry ethyl octanoate, which smells fruity, wine. The science ↓
Black Bean Soup
Ingredients
Directions
Prepare the beans
Soak the black beans overnight.
In the morning, boil the beans until they are soft.
Make the soup
Add pieces of corned beef to the pot and boil until the beans are very soft.
Strain the mixture through a colander and return it to the soup kettle.
If the soup is too thick, add warm water to reach the desired consistency.
Season with pepper and ground cloves.
Before serving, stir in the chopped hard-boiled eggs.
Add wine for flavor if desired, but the soup is good without it.

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 and thicken it as they break down during boiling.
- Corned beef
- Adds salty, savory meat flavor to the broth as it simmers with the beans.
- Hard-boiled eggs
- Add soft, mild richness and body when stirred into the hot soup.
The step that matters
Boil the beans until very soft. Beans that are not fully softened stay firm and grainy, and they cannot break down to give the soup its body. Cooking them long enough lets the starches release and thicken the liquid.
Swap the beans
How well each one fits the dish's main ingredients (beef, pepper, clove, egg, wine):
- Beansthe original
- Chestnutfits about as well
- Chickpeafits about as well
- Walnutfits about as well
Fit is the average pairing score against beef, pepper, clove, egg, wine. Candidates are from the same food group and used in at least 100 recipes.
