Why it works: Beans and carrot match in chemistry and in kitchens. They rank in the top 4% of all ingredient pairs, and cooks put them together in 1,443 recipes. Both carry 2-isobutyl-3-methoxypyrazine, which smells green bell pepper, earthy. The science ↓
Bean Soup
Ingredients
Directions
Prepare the beans
Soak the beans in cold water overnight.
In the morning, drain and wash the beans in fresh water.
Simmer the soup
Put the beans into a soup kettle with the beef stock.
Bring to a boil, then reduce heat to simmer for at least 3 hours.
Two hours before serving, add the sliced onion and carrot.
For a smoother soup, strain through a colander before serving.

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 as they soften and release starch during long simmering.
- Beef stock
- Supplies the liquid and savory flavor that the beans cook in.
- Onion
- Adds aromatic sweetness and depth as it softens into the broth.
- Carrot
- Adds mild sweetness and body as it cooks down in the soup.
The step that matters
Simmering the beans gently for at least 3 hours. A rolling boil can break beans apart and cloud the broth, while a gentle simmer lets them soften evenly until tender.
Swap the beans
How well each one fits the dish's main ingredients (beef, onion, carrot, butter, pepper):
- Beansthe original
- Sesamefits about as well
- Peanutfits less well
- Black-eyed peafits less well
Fit is the average pairing score against beef, onion, carrot, butter, pepper. Candidates are from the same food group and used in at least 100 recipes.
