Why it works: Beans and pepper are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 4,733 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
White Bean Soup
Ingredients
Directions
Prepare the beans
Soak the beans in cold water overnight.
Put the beans in a saucepan and cover with water, adding more if necessary as they swell.
Make the soup
When the beans are soft, ladle them out and pass through a colander back into the saucepan.
Add pepper, salt, and butter, stirring in a little water if the soup is too thick.
For added flavor, include a boiled mutton or ham bone.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- White beans
- Provide the main body of the soup as they soften and break down into a thick purée.
- Butter
- Adds richness and a smooth, rounded mouthfeel to the finished soup.
The step that matters
Adding water as the beans swell. Dried beans absorb a lot of water as they cook, and if they are left uncovered they can be exposed and cook unevenly. Keeping them covered with water ensures they soften evenly and the soup does not become too thick or scorch.
Swap the beans
How well each one fits the dish's main ingredients (pepper, butter, mutton):
- Lima beansfits about as well
- Peasfits about as well
- Walnutfits about as well
- Beansthe original
Fit is the average pairing score against pepper, butter, mutton. Candidates are from the same food group and used in at least 100 recipes.
