Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Turtle beans (black beans)
Break down during long cooking and, pressed through a colander, thicken the soup body.
Soup bone
Releases savory flavor and body into the water during the long simmer.
Powdered cloves
Adds warm, aromatic spice flavor to the soup.

The step that matters

Adding the cloves, salt, and pepper halfway through. Cloves are strongly aromatic and can turn bitter or overpowering if cooked too long, so adding them when the beans are half done lets the flavor develop without dominating. Salt added partway also seasons the broth as it reduces.

Swap the beans

How well each one fits the dish's main ingredients (clove, pepper, egg, lemon):

  1. Chickpeafits better
  2. Walnutfits about as well
  3. Chestnutfits about as well
  4. Beansthe original

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