Why it works: Allspice and clove match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 7,874 recipes. Both carry estragole, which smells anise, licorice. The science ↓
Black Bean Soup
Ingredients
Directions
Prepare
Soak the black beans overnight.
Drain the beans and boil them in fresh water with baking soda, ham, allspice, cloves, parsley, and thyme.
Brown the onion in butter and add it to the soup.
Simmer and finish
Simmer for 4 hours or until the beans are soft, adding cold water as needed to maintain about 2 quarts.
Press the soup through a sieve.
Stir in salt, pepper, cayenne, juice from the lemon, chopped hard boiled egg, and sherry wine if using.

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 long simmering.
- Baking soda
- Raises the pH of the cooking water, helping the beans soften more quickly.
- Ham
- Adds savory, salty flavor to the broth during the long simmer.
- Butter
- Carries the browned onion flavor and adds richness to the soup.
- Onion
- Browned first to add sweetness and savory depth to the soup.
- Lemon
- Juice adds acidity that brightens the heavy, earthy flavor of the beans.
The step that matters
Simmer until the beans are soft, topping up the water. Dried beans need long, steady simmering to become fully tender. Letting the liquid drop too low can leave beans firm and scorch the bottom of the pot, so cold water is added to keep the soup at its intended volume.
