Why it works: Beans and potato match in chemistry and in kitchens. They rank in the top 5% of all ingredient pairs, and cooks put them together in 655 recipes. Both carry 2-isobutyl-3-methoxypyrazine, which smells green bell pepper, earthy. The science ↓

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

What each ingredient does

Dried beans
Form the body of the soup and thicken the broth as they break down during simmering.
Fresh water
Provides the cooking liquid that softens the beans and forms the broth.
Potatoes
Add starch and body to the soup when added near the end of cooking.

The step that matters

Simmer slowly and keep the liquid topped up. A gentle simmer cooks beans evenly without bursting their skins, while a boil can break them apart. Letting liquid reduce too far exposes the beans and concentrates the broth, so adding hot water keeps the beans submerged and cooking evenly.

Swap the beans

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

  1. Beansthe original
  2. Chickpeafits about as well
  3. Black-eyed peafits less well
  4. Lentilsfits less well

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