Why it works: Butter and bread are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 27,232 recipes. Both carry delta-decalactone, which smells sweet, creamy. The science ↓
Bean Soup
Ingredients
Directions
Prepare the beans
Soak the beans overnight in water.
In the morning, drain the beans and add 2 quarts of boiling water. Once it boils, pour off the water and add 2 quarts of fresh boiling water and the baking soda.
Cook and strain
Boil until the beans are very soft, then press them through a sieve back into the kettle.
Finish and serve
Add salt, pepper, and cream (or milk and butter) to the beans.
If the soup is too thick, thin it with a little water.
Serve with slices of toasted bread.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Dried white beans
- Form the body of the soup once softened and pressed through a sieve.
- Baking soda
- Raises the cooking water's alkalinity, helping the beans soften more quickly.
- Cream or milk
- Adds richness and a smooth, creamy texture to the soup.
- Butter
- Adds fat for richness and a silky mouthfeel in the finished soup.
The step that matters
Boil until the beans are very soft. Beans that are not fully softened stay grainy and will not press smoothly through the sieve. Cooking until they are very tender lets the starches break down so the purée is smooth.
Swap the beans
How well each one fits the dish's main ingredients (pepper, cream, butter, bread):
- Lima beansfits about as well
- Almondfits about as well
- Chestnutfits about as well
- Beansthe original
Fit is the average pairing score against pepper, cream, butter, bread. Candidates are from the same food group and used in at least 100 recipes.
